I went to buy Injustice: God's Among Us from Gamestop a few weeks ago for my ex. The guy behind the counter rings me up, puts the game in the bag and as I'm walking out of the store, I look in the bag and notice the game isn't sealed.
Sure enough, they sold me an opened copy, I check the receipt and he sold it to me as "NEW".
I turn right back around (still in-store), and ask the guy "why is this opened?" and he responds: "oh, I can give you a sealed copy if you want."
I respond: "Umm...I paid you for a new copy, no?" and he just tells me "it's the same thing" as he switches the copies for me.
Never had a good experience at that store and that just solidified me never shopping there again.
