50% off Case-Mate Pop case for Samsung Galaxy S2 (AT&T)

I saw that the AT&T site has this Samsung Galaxy S2 case on sale. It's the Case-Mate Pop Case (with the kick stand) on sale for $18. I went to the store today to see if they would price match their website and it actually rang up as $17.50 (half off), as it is normally $35. So I paid just under $19 out the door for this case.

I have looked online and found equivalent pricing, or slightly lower on Amazon. But I was worried about ordering from them and having them ship me the case for the international version, since I read reviews that the cases for the international and the US version do not size up right. At least in the store, I know it's the right version. Also, the rep told me that I have a 1 year warranty with the case, so I can just take it back to the store if I have any problems.
I have it on my phone now and it's great. Doesn't feel too bulky and it's got a good grip from the rubber sides, so don't have to worry about slipping. But the best part is the kickstand, great for watching videos or playing games.
