If you've got a console you're looking to trade in, GameStop is willing to give you a little something extra for it. Until tomorrow, GameStop is running a "Fund Your Holiday" campaign where they'll give you an additional $50 for your console trade-ins.

Trade-in consoles have to be in "full working condition" to receive the extra $50, and this offer doesn't stack with any other promotions GameStop may be offering. If your console fits the bill, you will receive the additional $50 on a gift card.

Only the following products are eligible for the "Fund Your Holiday" trade-in promotion:

• Video Game Platforms
• Xbox One
• PlayStation 4
• PlayStation VR
• Wii U (32GB model only)

• Apple Devices
• iPhone 6
• iPhone 6 Plus
• iPhone 6s
• iPhone 6s Plus
• iPad Mini 2, Mini 3, and Mini 4
• iPad 4
• iPad Pro

• Android Devices
• Samsung Galaxy S5
• Samsung Galaxy S6
• Samsung Galaxy S7

Trade-in values range widely but expect already 25-30% of the MSRP plus $50. So the PlayStation 4 and Xbox One have a trade-in value of $125, and with the $50 promotion you'd end up getting $175 all told.

If this offer appeals to you, then act fast. The GameStop "Fund Your Holiday," campaign ends tomorrow.
