Shops that trade

Anyone know of any games shops in Dublin that exchange/trade-in/buy games?

I have some on brand new ones on PC format and I want to change them to PS2.

I know Game in cork does it
i know theres a game in dublin, think its on henry st, presume they have the same policy regarding, taking used / 2nd hanf games

Xtra vision in Sligo buy your games back off you so id say the ones in dublin do aswell.
