As opposed to finding receipt and standing in line for an hour to hope they have a record. Costco is easy compared to most outfits but is a half hour away. Anyway just put item back in box it came it and ask to return, they email you a shipping label and you either take it to nearest shipper or have them come by and pick it up.
Anyway sounds like you have never tried to use Amazon because they will have items that you will never find in any local store. If you want a rally odd item look on eBay. I actually only go to town for perishable food items everything else is delivered to my home and as a bonus I practically heat my house with the card board boxes.
You would be completely wrong about me. I use amazon and STARTED with eBay for what it was originally meant for, OLD stuff not returnable anyway. My husband is very big on amazon so we have plenty experience as a whole.
I do everything I can to avoid buying on-line though (again, thats catalog purchasing, its nothing new). If I buy in real life I get it immediately and ensure it is in good shape so those alleged lines are moot. Even if I do return in person it is almost never a long wait, and no problem. My area is heavily populated so yes, we have many of each store around so no problem there, especially when it is on the way to work, etc. If one is a complete hermit who insists on staying in the house, yes, I guess that would be inconvenient.
Sorry, I dont want to figure out how to put something back in its highly engineered packaging and then go to the mail store (also a good wait). The ROI IMO is poor.
