I have a suggestion for Costco. Stop being so liberal on your return policy. I am so appalled at how these tourist bring coolers, swim fins, mask and even 1/2 gallons of milk back on their way to the airport. Really people!!!! Don't you folks have any shame in doing that??? Just because your done with your vacation doesn't give you the right to dump your USED merchandise back on a retailer that we rely on to keep prices a little lower for our families!!!
