Accounting Policies [Abstract]
General	Note A – General The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission’s (the “SEC”) rules and regulations. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. For further information, refer to the consolidated financial statements and related notes included in the AutoZone, Inc. (“AutoZone” or the “Company”) Annual Report on Form 10-K for the year ended August 25, 2012. Operating results for the twelve and thirty-six weeks ended May 4, 2013, are not necessarily indicative of the results that may be expected for the fiscal year ending August 31, 2013. Each of the first three quarters of AutoZone’s fiscal year consists of 12 weeks, and the fourth quarter consists of 16 or 17 weeks. The fourth quarter for fiscal 2013 has 17 weeks and for fiscal 2012 had 16 weeks. Additionally, the Company’s business is somewhat seasonal in nature, with the highest sales generally occurring during the months of February through September and the lowest sales generally occurring in the months of December and January. Recently Issued Accounting Pronouncements: In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (“AOCI”) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. The Company does not expect the provision of ASU 2013-02 to have a material impact on its consolidated financial statements. This update will be effective for the Company at the beginning of its fiscal 2014 year.
