Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company and include the accounts of Advance Auto Parts, Inc. ("Advance"), its wholly owned subsidiary, Advance Stores Company, Incorporated ("Advance Stores"), and its subsidiaries (collectively, the "Company"). All intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the financial position of the Company, the results of its operations and cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, have been condensed or omitted based upon the Securities and Exchange Commission ("SEC") interim reporting guidance. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for Fiscal 2014 (filed with the SEC on March 3, 2015). The accounting policies followed in the presentation of interim financial results are consistent with those followed on an annual basis. These policies are presented in Note 2 to the consolidated financial statements included in the Company’s Annual Report. The results of operations for the interim periods are not necessarily indicative of the operating results to be expected for the full fiscal year. The first quarter of each of the Company's fiscal years contains 16 weeks. The Company's remaining three quarters consist of 12 weeks, with the exception of the fourth quarter of fiscal 2014 which contained 13 weeks due to the 53-week fiscal year in 2014. The Company's next 53-week fiscal year is 2020. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Acquisition On January 2, 2014, the Company acquired General Parts International, Inc. ("GPI") in an all cash transaction. GPI, formerly a privately-held company, is a leading distributor and supplier of original equipment and aftermarket replacement products for Commercial markets operating under the Carquest and Worldpac trade names. As of the acquisition date, GPI operated 1,223 Carquest stores and 103 Worldpac branches located in 45 states and Canada and serviced approximately 1,400 independently-owned Carquest stores. The Company acquired all of GPI's assets and liabilities as a result of the transaction. Under the terms of the agreement, the Company acquired all of the outstanding stock of GPI for a purchase price of $2,080,804 (subject to adjustment for certain closing items) consisting of $1,307,991 in cash to GPI's shareholders, the repayment of $694,301 of GPI debt and $78,512 in make-whole fees and transaction related expenses paid by the Company on GPI's behalf. The Company included the financial results of GPI in its consolidated financial statements commencing January 2, 2014. Segment and Related Information As of April 25, 2015, the Company's operations are comprised of 5,235 stores and 115 distribution branches, which operate in the United States, Canada, Puerto Rico and the U.S. Virgin Islands primarily under the trade names “Advance Auto Parts,” "Carquest," "Autopart International" and "Worldpac." These locations offer a broad selection of brand name, original equipment manufacturer ("OEM") and proprietary automotive replacement parts, accessories, and maintenance items primarily for domestic and imported cars and light trucks. While the mix of do-it-yourself ("DIY") and do-it-for-me ("Commercial") customers varies among the four store brands, all of the locations serve customers through similar distribution channels. The Company has begun implementation of its plan to fully integrate the Carquest company-operated stores and overall operations into Advance Auto Parts by the end of fiscal 2017 and to eventually integrate the availability of all of the Company's product offerings throughout the entire chain. The Company's Advance Auto Parts operations are comprised of five geographic areas which include the operations of the stores operating under the Advance Auto Parts, Carquest and Autopart International trade names. Each of the Advance Auto Parts geographic areas, in addition to Worldpac, are individually considered operating segments which are aggregated into one reportable segment. Effective in the first quarter of 2015, the Company expanded from three geographic areas, which previously comprised the Advance Auto Parts and Autopart International operations, to five geographic areas inclusive of the Carquest operations, such that Carquest is no longer a separate operating segment. Included in the Company's overall store operations are sales generated from its e-commerce platforms. The Company's e-commerce platforms, primarily consisting of its online websites and Commercial ordering platforms, are part of its integrated operating approach of serving its DIY and Commercial customers. The Company's online websites allow its DIY customers to pick up merchandise at a conveniently located store location or have their purchases shipped directly to them. The majority of the Company's online DIY sales are picked up at store locations. Through the Company's online ordering platforms, Commercial customers can conveniently place orders with a designated store location for delivery to their places of business or pick-up. New Accounting Pronouncements In April 2015, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Updated, or ASU, 2015-3 "Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs". ASU 2015-3 simplifies the presentation of debt issuance costs by requiring such costs be presented as a deduction from the corresponding debt liability. The guidance is effective for financial statements issued for reporting periods beginning after December 15, 2015 and interim periods within the reporting periods and requires retrospective presentation; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows. In August 2014, the FASB, issued ASU 2014-15 “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern." This new standard requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity's ability to continue as a going concern. This ASU is effective for annual periods ending after December 15, 2016, and interim periods thereafter; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows. In June 2014, the FASB, issued ASU 2014-12 “Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The amendments in this ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows. In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers." This ASU is a comprehensive new revenue recognition model that expands disclosure requirements and requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. Public entities are currently required to adopt ASU 2014-09 during annual reporting periods beginning after December 15, 2016 and interim reporting periods during the year of adoption; however, the FASB issued an exposure draft on April 29, 2015 that would defer the effective date of ASU 2014-09 by one year with public entities permitted to early adopt for reporting periods beginning after December 15, 2016. We are currently evaluating the impact of the adoption of this guidance on the Company's consolidated financial condition, results of operations and cash flows. In April 2014, the FASB issued ASU No. 2014-08 "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of Equity", which amends the definition of a discontinued operation in Accounting Standards Codification, or ASC, 205-20 and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued operations criteria. The new guidance changes the definition of a discontinued operation and requires discontinued operations treatment for disposals of a component or group of components that represents a strategic shift that has or will have a major impact on an entity’s operations or financial results. The Company adopted this guidance effective January 4, 2015. The adoption of this guidance affects prospective presentation of disposals and did not have an impact on the Company's consolidated financial condition, results of operations or cash flows.

Basis of Presentation:

The accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company and include the accounts of Advance Auto Parts, Inc. ("Advance"), its wholly owned subsidiary, Advance Stores Company, Incorporated ("Advance Stores"), and its subsidiaries (collectively, the "Company"). All intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the financial position of the Company, the results of its operations and cash flows have been made.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, have been condensed or omitted based upon the Securities and Exchange Commission ("SEC") interim reporting guidance. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for Fiscal 2014 (filed with the SEC on March 3, 2015).

The accounting policies followed in the presentation of interim financial results are consistent with those followed on an annual basis. These policies are presented in Note 2 to the consolidated financial statements included in the Company’s Annual Report.

The results of operations for the interim periods are not necessarily indicative of the operating results to be expected for the full fiscal year. The first quarter of each of the Company's fiscal years contains 16 weeks. The Company's remaining three quarters consist of 12 weeks, with the exception of the fourth quarter of fiscal 2014 which contained 13 weeks due to the 53-week fiscal year in 2014. The Company's next 53-week fiscal year is 2020.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
