Subsequent Events [Abstract]
Subsequent Event	Subsequent Event In March 2012, subsequent to the end of fiscal 2012, we announced a transformation strategy consisting of a series of actions intended to improve operating performance. The announced actions include closure of approximately 50 large-format Best Buy branded stores in the U.S., changes to the store and corporate operating models, and other measures intended to reduce costs associated with product life-cycle management and supply chain. The costs of implementing the changes primarily consist of lease exit costs, employee severance and fixed asset impairments. We will begin initiating the announced actions in the first quarter of fiscal 2013 and expect to complete the actions by the end of fiscal 2013. We expect to incur total pre-tax restructuring charges of between $300 and $350 related to the actions, of which between $30 and $40 will be non-cash. Given the timing of these actions, we estimate that between $140 and $160 of the charges will be recorded in the first quarter of fiscal 2013, consisting primarily of employee severance and fixed asset impairments triggered by our change in the intended use of those assets resulting from the strategic actions. The estimated costs associated with lease commitments on vacated stores will be recognized when stores are closed, expected to be throughout the remainder of fiscal 2013. The timing of lease payments for vacated stores is generally expected to follow the original lease terms, except to the extent we reach agreement with landlords for an alternative settlement. The amount of the restructuring charges noted above are estimates, and the actual charges may vary materially based on various factors, including but not limited to the following: the timing of store closures; level of employee terminations; factors relating to real estate, such as sale proceeds and the timing and amount of sublease income and other related expenses; and changes in management’s assumptions.
