Trade in a 2DS, 3DS, or 3DS XL at GameStop and get $100 towards a New 3DS XL
GameStop is running a new trade-in promotion for the New 3DS XL. If you trade in a 2DS, 3DS, or 3DS XL (or even a Vita), you’ll receive $100 that can be used towards the purchase of Nintendo’s latest handheld. It’s currently unclear when the offer will expire. Source
