Rarely shop at Gamestop and when I did, it was online. Best Buy has been my go-to, especially with Gamers Club Unlocked that just ended last month for me.
I was irritated by what they consider "brand new", this happened to me back when I wanted Sega GT for OG Xbox.
Customer: "Do you have <insert game name>?"
GS: "Sure"
Customer: Great, I'd like a copy
GS: <Gets disc, puts it in the case, about to charge>
Customer: "Wait, I want a brand new copy."
GS: "Oh, the disc is fine, it's the same thing".
Customer: "No thanks." <leaves>
