Picking up a new PlayStation 4 Slim or Xbox One S doesn't have to cost a full $300.

GameStop has announced a new, limited-time trade-in offer where you can get either system for $175. The retailer will pay you $125 for your PS4 or Xbox One when you apply the credit towards the purchase of a new console, meaning you can get either new system for $175 before tax.

This offer doesn't last forever, as it runs now through September 20. As always, it's a good idea to contact your local GameStop to learn more about the specifics of trade-in offers and how to get the full credit.

The Xbox One S launched at the start of August, while the PS4 Slim debuted today, September 15. Both systems are smaller than the launch models. You can see a comparison in this gallery.
