Trading in my game (tamagotchi wii) to GAME shop how much allowance wouldd I get back? - allowance game

When I changed my game Tamagotchi (Wii) for storage of game, but how much subsidy that comes?
Because I really the game is over - the people of the town and asked me if I could cheaper than € 20 - € 40
The game is in very good condition, and a small incision on the side of the box, which would make any differance?
Thank you for your time and answer:)
