Local shop with hobby boxes

[SMLV1]

I work close to a pawn/discount/value shop. Its a shop where you set up your own little store/area and sell your item. There are a few hobby boxes of cards in this one glass case....should i take a gamble and pick one of these up?

If they are sealed you should be Okay. Many people take scales and weigh the packs to see if any redemption cards are inside, but from what I've seen of those listed, the auto's would weigh the same still?!? How much are they other places?
