3ds for dsi at gamestop 75 bucks off?

common sense tells me that you will not b able to trade broken or not working items and if they do accept it the trade in price will b stupidly low, having said that any amount off the 3ds price is good and there's no point in keeping a broken ds. my advice is find out how much it costs to repair and offer it to a friend or family member to have for free if they want it to fix it.
