I just finished reading the latest EGM and one of the writers entered a Gamestop to purchase a game. After a series of sales questions we all are familiar with (preorder, update your card, etc.) the person was offered the chance to buy a used copy for $5 less. The writer went off on the sales person, telling them that he wanted to support the industry.

I know similar topics like this cropped up before but I think this is a bit different. Do you try and buy games new (even at sales) to support developers to continue to make the games you like or do you take the opportunity to buy used from "retail" used game chains like Gamestop to save some cash?
