Picture this:
You are a collector of a certain mass produced product. You frequent a store looking for these products often. You know how much they cost and the price never waivers. You buy a case of 12 of these items from said store but the ignorant cashier rings up only one of these items, not the entire case. You notice this gross mistake since the case should cost $140 and instead they charge you $10. If you decide to not say anything, is this theft and does this show a lack of integrity?
End of question.

Beginning of my opinion
This happened to someone I know (not even a friend) and they took advantage of the situation. I am trying to tell them that what they did was stealing since they knew of the mistake but let it slide. I likened it to giving a cashier a $5 and they give you change back for a $20. While this was a big corporation that made the mistake, I think it was just as wrong as if they'd gone in and stolen 11 of these collectibles.
