If you’re looking for a certain type of vitamin or supplement for your pet, be sure you can find it at Costco, as they have a wide variety of such products. But wait, there’s more. While PetSmart and Petco do not receive returns when it comes to vitamins and supplements bought from their stores without the original packaging and a receipt and within a 60-day return limit, Costco has no such rules.
They take anything back, anytime, for any reason. More than that, you can also return flea and tick prevention items, such as collars, without struggling to find the receipt.
