In the last two months I unexpectedly was charged for three UPS adjustments for return shipping after I prepaid via Amazon for the return shipping labels (~$7 each). Two chargebacks were for a little over $40 and the last one a few days ago was for $53!! All three items were for the return of a single book costing me $9.55 for a USPS Priority Mail Flat Rate Padded Envelope (again I only purchase shipping through Amazon). UPS is gouging Amazon and its book sellers, and no one is fixing this problem! I reported the first two chargebacks a few times and get the standard AI BS. Finally, one helpdesk person told me to contact UPS. Am I supposed to take the fight to Amazon's return shipping contractor? I think not. I think this has become a serious legal issue that involves price gouging, unreasonable fees. etc. Then, Amazon just dips into my bank account to take these overcharges without helping with resolution or investigation that these are not my charges! I am a single owner of about 400 art books and a couple hundred books in other genres I've collected over 40 years. I am not selling thousands of books a week. Maybe 2 or 3 if I'm lucky. I truly have reached the point that I am paying to send my books to people. And some buyers are lying about their refund requests... but we won't' even try to open that Pandora's box right now. There are legions of buyers out there that use things they bought on Amazon knowing they can return them no questions asked, and in most cases, can keep the items as well. I heard people at work talking about how easy it is to get free stuff via Amazon due to their liberal return policy. It is so infuriating, and it seems Amazon is just passing these problems on to their smaller vendors to deal with. And now we have UPS with their $40 and $50 chargebacks for return shipping on single books. Three times in two months is not a one-off error problem. It is deliberate and constant in my opinion.
