Hey,
I just wanted to let everybody know about a problem I ran into once and was able to resolve.
It seems that Gamestop used to try to make you take the *cheapest* games for free. Thus, if you bought 3 $50 games and 3 $10 games, they would try to force you to pay for the $50 games and give you 2 ten dollar games for free.
After being treated rather rudely, I called their internet 800-number and talked the guy into giving me the number of their Region Manager. When I got in touch with her and explained the situation (the rationale behind penalizing somebody $40 for buying 3 extra games is ludicrous) she was very friendly and told me that she was not happy with her greedy store managers. I have not had a problem since at any of the stores in my area.
I did, however, have a problem with one of the stores in Kansas City. They were very insistant. When I told the Manager my story, she caved. Just wanted to let you guys know you do have some options if the employees don't know or are a little on the greedy side. You can tell them that their Region Managers have clarified the issue and if they want to call them they can. I have also been told that there is an email that goes out with the Buy 2, Get 1 sale and it is detailed correctly in the email.
