California Distribution Center [Member]
Lessee, Lease, Description [Line Items]
Lessee, Operating Lease, Description	In November 2017, we entered into a synthetic lease arrangement for a new distribution center in California. The term of this lease commenced in the second quarter of 2019 and will expire after five years. Under the prior accounting standard, this lease was accounted for as a capital lease due to certain construction period considerations; therefore, it was reflected in both our balance sheet and our future minimum lease obligations disclosure. As the lease commenced in the second quarter of 2019, we assessed the lease classification of the agreement and determined it was an operating lease under ASC 842; therefore, the lease is included in our operating lease right-of-use assets and operating lease liabilities in the below table as of August 3, 2019. The annual lease payments are approximately $7 million for the duration of the term. Additionally, this arrangement includes a residual value guarantee.
