The upside of shopping at Costco is bulk savings. The down side? I still haven't found one…except for the danger of dropping 200 pound shampoo, soap, and conditioner bottles on your toes while showering.
The only other downside of shopping at Costco is limited to those who are forced to shop at the location in Norwalk, California. Waiting for an organ transplant is faster than the lines at this location, really though.
The good news is that there's an easy remedy to the bulk-sized bottle dilemma, see below.
As far as the long lines, move closer to a different Costco location.
