Does anyone know the Canadian trade-in values for both ICO and SotC? I would assume ICO would be semi-high since it's a rather rare game. I'm thinking of trading in my copies for the upcoming PS3 Collection version of the two.
EBgames? Three and a half lolz. ICO may get you 7 bucks tops, but there are copies of SotC filling up bargain bins out there; that will give you 1 at most.
Your best bet to get the most bang out of your discs is to hock them off to kajiji and hope they don't already know the collection is coming out.
Of course I'd think you should be able to get more than $25 for a complete good condition copy of Ico, even with a re:release coming it's a collectable game.
EB games gives very little for PS2 games, I would go with Poiuiu's suggestion and sell them online, try Ebay or Craigslist even. You would be guaranteed to make more than anything EB will give you.
ICO was worth quite a bit when I bought the game (and later resold thanks to it's enduring value) but I imagine the news of the collection made the value plummet.
