I think it would be cool if we could have kind of a "shopping cart" system on our game collection page. For instance, you would look at your game collection, then could go through and check a handful of games, and do "add to cart". Then you could view the cart and see the combined trade-in value at Gamestop, Amazon, etc. That would be very helpful when trading in a group of games. A cart system would make it easy to quickly run different sets of comparables to make sure we are maximizing the trade value when different promotions are going on. Right now I have to go to each individual game and note the trade value in Notepad. Granted this isn't a huge deal for me to do, but I thought I'd throw the suggestion out there.
