If you're looking for an alternative to GameStop, check out Rakuten.com. The online retailer is currently offering 20 percent off sitewide with promo code CYBER20 (formerly, BF20). Earlier, we found at least one seller offering the console for $310 and the code brought my in-cart price down to $250. But this was a third-party seller, not Rakuten proper. Other third-party vendors have marked up the starting price to $329 (which would still get you down to $263), but prices have been climbing throughout Monday. And supplies are definitely limited.

Looking for a Switch alternative? Walmart has $20 off the smaller, even more portable 2DS XL.
