David,
I don't know either. But I do know there's a lot of open box items available on Ebay. When I purchased some of them, I found the accessories were missing or faulty, but the main item was good. I got a steep discount for that. Once I was in a store and I asked them about open box items. They said I would have to ask them. They did not advertise lower priced open box items, but again a person could get a better price if you asked and they had it available.
Overall, I think USA consumer laws and store policies are liberal in that refunds and returns are common. In stores, there's a special place for people to return items. I don't know if they even have to give a reason, as long as they have a receipt. From what I read, it depends on the store policy and state laws.
So, that got me thinking.... So I did more investigating.... AI said that in 2023 14.5% of all consumer goods were returned in the USA (online and in-store purchases). Wow...that's shocking.
Edit again: I found that in the UK consumer items are returned at a even higher rate for online purchases. I never thought it would be so high.
