Where can you find this stuff at?
Hmmm... I don't know if I should answer this, the way you ended that sentence...
Remember: A Preposition is not a good thing to end a sentence with.
May I suggest, "Where can you find this stuff?" as an alternative.
Also: Albertsons, Kroger stores, Safeway, Piggly Wiggly, AM/PM, Super Walmarts, K-Marts, and Targets... I've seen it pretty much everywhere. Even at my house.
