Shop GAME will give you a trade-in price of £190 on the £196.99 Nintendo 3DS if you bring it back within a month of buying it.
This price is guaranteed only if you trade the Nintendo 3DS in by 25th April, MCV reports.
There are a few conditions, however. The order must be placed online, and you must keep hold of your packing receipt. GAME's in-store Nintendo 3DS price is £220.
If you want to trade for cash, you'll get £180 effectively meaning the Nintendo 3DS, which goes on sale on 25th March, costs £17 to rent for a month from GAME.
It's all part of GAME's Play Now / Trade Later offer. A similar promotion was attached to Atari's online-enabled racer Test Drive Unlimited 2 GAME guaranteed a buy back price of £34.99 on the 40 quid game.
