Louis Vuitton sold at... COSTCO ?!?

What is Costco?? Obviously a shop but what kind? Upmarket or a cheapo shop??
Costco is a wholesale department store / pharmacy / supermarket. They sell food, books, household items, clothes, everything... Eg. instead of buying 1 can of soup for $2.50 you can go to costco and buy a box (24 cans) for $35
etc
You need to pay a membership to shop there ($40 a year I think)...and the prices are good but you have to usually buy in bulk (for food and household stuff...not for clothes, books, DVD's, electronics, jewelry, etc)
