Amazon will accept returns, but not like Costco will or sears did.
Sears would exchange any broken craftsman tool for a new one even decades after purchase. Costco is much the same. Used, year old stuff with missing parts will gladly be refunded in full.
To be fair to Costco you have to understand that the way they do that is they just send the item back to the vendor and deduct it from the next purchase. The vendors only option is to not sell stuff to Costco anymore.
