Subsequent Events [Abstract]
Subsequent Events [Text Block]	SUBSEQUENT EVENTSIn March 2021, we signed a definitive agreement to acquire Edmunds, one of the most well established and trusted online guides for automotive information and a recognized industry leader in digital car shopping innovations. With this acquisition, CarMax will enhance its digital capabilities and further strengthen its role and reach across the used auto ecosystem while adding exceptional technology and creative talent. Edmunds will continue to operate independently and will remain focused on delivering confidence to consumers and excellent value to its dealer and OEM clients. Additionally, this acquisition will allow both businesses to accelerate their respective capabilities to deliver an enhanced digital experience to their customers by leveraging Edmunds’ compelling content and technology, our unparalleled national scale and infrastructure, and the combined talent of both businesses. We expect to pay for the transaction with a combination of cash and equity for a purchase price that implies an enterprise value of $404 million, inclusive of our initial investment. The transaction is subject to certain conditions to close typical for a transaction of this nature. We anticipate this transaction will close in June 2021 and expect Edmunds’ financial results to have an immaterial impact to CarMax’s earnings per share in fiscal 2022.
