Accounting Changes and Error Corrections [Abstract]
Correction of Immaterial Errors	Correction of Immaterial Errors In connection with the preparation of the January 31, 2015 consolidated financial statements, the Company determined that certain payments directly made to customers, which were previously included in selling, general, and administrative expenses, should instead be reflected as decreases to net sales. The current year Condensed Consolidated Statement of Operations properly reflects payments directly made to customers as decreases to net sales. While the amounts included in prior year were considered to be immaterial, the Company elected to revise the presentation of previously reported amounts to be consistent with the presentation for the quarter ended April 30, 2015. The change resulted in decreases to net sales, gross margin and selling, general, and administrative expenses of $147,000 for the quarter ended April 30, 2014.
