How do you convince gamestop to give you more money for your games?

i want to sell my psp games. but i know they might rip me off. so i wanna c how i can make them give me more.

or else what other store can i sell my games toHow do you convince gamestop to give you more money for your games?
try a bold face lie. if they offer 5 dollars for a game, say best buy is offering 6 dollars for it. you can also use the reward card to get trade-in bonus. it's not much, but it is slightly more than what you're offered.



best buy and amazon are the only 2 stores that i know that buys used games so if you want more from gs, use them and have them try to outbid each other.
