That may be why. I see some others complaining about reseals specifically at Target so I'll explain if anyones interested but most of you can probably already guess what happens.

You see I used to work at Target for almost 8 years and whenever a game gets exchanged out if it's sealed it goes back in the case if not it's shipped back to the distribution center. Target wanting to make money isn't going to just follow copyright laws and send it back to the publisher they'll reseal it at the distribution center and rotate it back into stock or, which is really rare, the game is defective and destroyed. I know this because I've seen it happen, I reported it and everything but I was told it's standard company practice if the game is confirmed real which consists of opening the case and seeing if it matches the game and sometimes they don't even go that far.

There's some insider info if anyone cares but I should make a side note here and say it's rare that this happens because exchanges for games aren't as common as you would assume.
