I have had an overall good experience here but one time one of the managers did not allow me to get 20% off the sale price of a video game with the Gamers club card, which was still active. I had always received the 20% off even on games that were on sale before. The sale price was online and they have always matched it and even later adjusted the 20% off as well. I am not sure why he only gave me the better deal of the two if this is what has always been the case. It was inconsistent. It was as if I was doing something wrong. I didn't feel as comfortable going there afterwards.
