Best Buy is offering a free $20 gift card to customers who purchase a Nintendo Wii U, according to a listing on the retailer's website.

A representative from Best Buy's corporate headquarters confirmed with Polygon that the offer is available for both online and in-store purchases. Online orders include free shipping and the promotion extends to all Wii U models.

For both online and in-store purchases, the $20 gift card will be mailed to customers separately one to two weeks after buying the Wii U.
