I found this interesting set of videos that was created by an ex-Gamestop employee talking about his experiences working for the company for over a year. It's a very humorous look at the whole thing, but also very eye opening as well. His main intent through the whole set is to try to inform people why they shouldn't shop at Gamestop.
his vids (NSFW due to language) are on Youtube, and can all be found here:

The whole set is about 90 minutes long, but I thought it was a worthwhile use of my listening time.
