Amazon defaults to the buyer and will screw over vendors in a heartbeat even when there is obvious buyer fraud. They don’t really want vendors competing with Amazon’s own sales, they only have them as a way around anti-trust laws.

We sent a customer a $60 video collection. It is the only such collection we sell. She claimed we sent something that was a different collection which is impossible. Amazon told her to keep the set refunded her the $60 sale price and shipping $4. So she got the videos and $64 refund. Amazon then kept the $20 commission on the sale for themselves.

Amazon deducted $64 from what they owed us, meaning they kept their $20 commission. And we had to buy a replacement video set for $22. So we had $86 stolen from us by this one fraudulent claim. Since Amazon keeps their very high commissions regardless of what happens they don’t give a damn.
