You might post over in services and see i anyone is willing to do this. But because of possible abuses sadly i don't think many will be willing. There is just a lot of possible bad things one could be a party to by accepting goods and then sending them to you.
The biggest thing is as the person who receives from amazon. You really don't know if the items you are getting and shipping funds came from legit source or stolen CC's etc.
Yes i understand, is there any sort of proof i could provide without divulging personal information?
I don't see any way to determine that the goods were legitimately purchased without showing an ID and credit card with a matching name. People may be willing to do it if you pay for it with bitcoin via gyft.com. This way, all you will have to show is a transaction ID for the amazon gift card purchase and a receipt showing that the items were purchased with the matching amazon card.
