I ordered a small food scale to replace one I thought I had lost in a move.

Of course the day the replacement arrived, my wife pulled the old one out of the closet she had stashed it in.

I went to return the one I just bought and Amazon simply said to keep it and they would refund me because it wasn't worth shipping back to them.

Obviously won't work for everything and I imagine if I do that very often they won't let me anymore, but it's the best return experience I've ever had.

I accidentally ordered $200 worth of items through prime pantry, 95% non-perishables (including 24pk Monster, Solo cups, paper plates/bowls) to my home in the MidWest instead of where I was at on the West Coast.

2 minute phonecall, said keep everything and instantly refunded the entire order as a credit (my choice)

Luckily had somebody to bring everything inside back home too, haha.

I use the "return at Kohl's" option for amazon items, and it has been super easy. Don't even have to box the item up.
