I and several other customers had to wait at least 15 minutes in line while the only two people in the store were helping two people, the first was a kid turning in his 3ds to get a PS4 and the second was some lady who was turning in her old phone and getting a new one activated (who buys their phone at gamestop?!), I have no idea how long it takes to do these two things because lucky for me a 3rd employee walked into the shop and after a few minutes opened the 3rd register and I was able to do my business and get out while the other two were still helping the same people who created a 15+ minute line.
AWFUL experience, they'll need to be giving away games next time I go to this location again.
