If you're not willing to part with your old DS Lite, the offer also extends to unwanted Xbox 360s, PSP-3000s and Wiis. To be honest, though, all of those are worth far more than the 75 quid you'd be getting in return. The DSi is released in Europe on April 3 and will retail for £150. That gives you plenty of time to hunt around the house for your old DS Lite box. You do still have it, right?
