If you're sure it's the same item, that's fine. Then again, they also sell cheaper versions of the same brand (Levi's for instance) that are pretty crap.

I actually went to Wal-Mart yesterday. There are things they do right (logistics) but in general, I don't buy a product at Wal-Mart unless I'm absolutely certain it's completely identical to a product I can get somewhere else, and that I know is durable.
