GAME will sell you the 3DS for £196.99 and offer you £190 store credit if you return it within the first month.
Those wishing to get their cash back will have to settle for the slightly lower figure of £180, MCV reports.
The 3DS trade-in deal will run until April 25, according to the site. Orders must be placed online and buyers will need to demonstrate their packing receipt when returning the portable to a GAME store.
Janco Partners analyst Mike Hickey said today he expects Nintendo to ship over eight million 3DS units in the West during the handheld's first full financial year on the market.
