Retailer GameStop's "summer of savings" promotion continues this week with a new Xbox One offer.

Everyone who buys a new Xbox One at GameStop will receive a $40 in-store gift card. The deal is available now through July 12 and it stacks on top of the retailer's existing trade-up offer.

GameStop will give you $150 in store credit toward the purchase of a new Xbox One or PlayStation 4 when you trade in a PlayStation 3 (120GB or greater) or an Xbox 360 (250GB of greater). This means you can get a new Xbox One for $200 (plus the $40 gift card) or a PS4 for $250.

Some of GameStop's other summer savings deals include:

Purchase a pre-owned original Xbox 360 for $59.99 after a mail-in rebate

Get 50% off pre-owned interactive game figures (Skylanders, Amiibo, Disney Infinity) with the purchase of three or more

Buy any pre-owned Wii and receive three pre-owned Wii games priced at under $10 for free

Buy any pre-owned original Nintendo DS or DSi and get three pre-owned DS games priced at under $10 for free
