I think it's a common practice, and I've done if quite a few times. But I do think there's a line between buying a game on clearance and trading it somewhere for more store credit -- or even Ebaying it -- and hording a ton of deals at one location, thus assing out all prospective other CAGs. I admit to hoarding once or twice in my time as a CAG, but have since learned my lesson: Share the wealth. Also, I find stuff like trying to return unopened games without a receipt -- purchased elsewhere -- for cash to be pretty detestable. I won't even talk about the PS3 ebay debate. But I guess all our moral lines and our consciences are different.
