Yes the lines are sometimes long at the checkouts and the parking generally sucks, but other than that I don't have any complaints about Costco. They have GREAT prices there (if you are willing to buy in bulk) and over all its just a fun store to walk around in. If you are a member (and you have to be to shop there) you will also get coupons in the meal to make their savings even greater (i.e. buy one get one frees, etc). A lot of my friends also shop here for diapers.
