Bought a new induction cooking pan. A nice one at $90. Didn't really pay much attention to who was selling it, just bought it like I do everything else from Amazon. It took about two weeks to arrive because it was from an independent seller, and was not 'Prime eligible'.
When it arrived, I took it out of the box and was immediately disappointed. It was really heavy, and the handle was shaped and angled in a way that made it hard to maneuver such a heavy pan. It'd be really difficult to do the usual flip and toss motions when cooking things.
I didn't want to spend $90 on a pan I would hate using, so I put it back in the box and requested a return.
That was when I found out exactly what the independent seller's return policy was. 1) I have to pay for return shipping (USPS best price was $38), 2) I have to pay them for the original 'free' shipping as well (no idea how much that was), and 3) I also have to pay a 25% restocking fee for an item in perfect resell-able condition. So in returning my $90 pan I figured I wouldn't get more than ~$30 back. I decided between being out $90 and having a pan or being out $60 and having nothing, I might as well keep it.
So I suppose that was a win for the seller - they successfully discouraged me from returning the item, which I'm sure would have cost them money. But it also discouraged me from buying anything on Amazon that isn't Prime, and it doesn't reflect well on Amazon that I had an experience completely contrary to their customer service values.
