We have had a costco for almsot two years and I have been very happy with them. I bought a GPS system right after they opened and last dec it quit working. Fortunately I had the receipt and the packaging and they simply had a higher up approve the return and gave me a credit and the model was disontinued so I just bought a nicer one that was actually cheaper. I was amazed they would do that after 18 months
I knew there were exceptions to the policy and thought hottubs were probably one (If you buy something like a laptop or camera there is a 90 day limit which is still generous). Here is their return policy from their site It sounds like a hot tub shoudl be covered however you would have to have the original box it came in (if it came in a box) and have it available curbside. Most people don't keep their original packaging (myself included I was just lucky with the gps that I had because other friends reported problems with them not working after 6 months). I think common sense should prevail here though. If you get the average useful life out of a product I wouldn't return it. If you buy a pair of jeans and you wear them every week and wash them every week and they last 5 years that is great That would mean 250 times of wearing them and 250 washes If they finally start to wear out, you got a good life out of them. I would never think of returning them.
here is their return policy for online purchases and I think it applies to the store as well:
