I buy a lot of stuff on Amazon, would be happy to get some money back. My concern is that if I take margin away from Amazon, and a take up a bunch of their CS time using Paribus, Amazon will classify me as a customer they would rather not have. And then, say, cancel my account if I end up returning bunch of stuff later, as they are rumored to do. So for Amazon, are price drop claims Amazon's official policy, or something that their CS allowed to do to appease customers? What kind of Amazon price drops qualify for refund? Also, if setting up a separate account to forward receipts to, the email will be different than one Amazon has for me. Is this a problem for your automated emails going from that account?
