Except for the fact that if it's true they're trying to "crack down on it", that would mean it's not something "bad" about the store at all. If they say nothing about it and it's truly YMMV then ok, try and and exploit it. But the second we hear (usually from a reliable source) that from the corporate level they're trying to put a stop to it...then we should also stop. At that point we're just being douchebags and potentially getting somebody in trouble for simply doing their job. Yes, if it doesn't explicitly say you can't do it on their policy you may want to raise a stick...but guess what if it doesn't explicitly say you CAN then they have the final say verbally.
I understand everybody wanting a good deal, but just think about it...clearly a deal like this isn't "meant to be", giving out games for $1-10 obviously isn't something they want to be doing.
