Returning oxygen sensor socket wrench at autozone?

I went to autozone and asked the guy for an O2 socket wrench and he sold me a regular socket wrench that wasn't compatible with my o2 sensor which I didn't realize until I got home. I already took the tags off the socket and the ratchet and tried using it once. I may have gotten a scratch on it in the process. My question is could I return the part anyway? I still have the receipt and the tags for the tools. On the back of the receipt it gives me the whole "if product has been used or opened" talk but is that really enforced? I hate that I had to spend 20 bucks on this and it wasn't the right one. If they say no could I try returning it to a different autozone? Has anyone returned an item after using it at autozone?
