Coach at Costco!?!?!?!

My local Sam's Club carries Coach, Fendi, and Prada. There are about two bags of each brand. They also sell Dior sunglasses. I don't think I'd ever buy from there... I feel safer buying from Coach.com and Coach boutiques.
 
I recently saw a couple of Coach and kate spade bags at Costco. They weren't cheap but they weren't even close to retail, and they were just lying about on a table with other miscellaneous things. ITA, I would never buy a "designer" bag from Costco, esp. if they aren't authorised to sell them.
