Amazon classes our product as non returnable (may be fair enough, as a food item, but goes out with 5 months shelf life minimum).

Product isn't allowed to be FBA as classed as a prohibited item

I NEVER get A to Z claim, I just get told when Amazon are refunding someone. I get it when it's someone panicking about a delivery missing, but I just had one refund that was bought mid November, and it's now 1 hour from March!

My SAFE - T claims are always rejected, mostly because I refuse to buy shipping through amazon.... even if they grant a refund 90 days over their '30 day policy'

I also can't claim anything for bad deliveries from courier because the orders are 'over 1 litre of liquids'.

Is there anything I'm doing wrong with amazon? Basically a customer has carte blanche of not sending back, not giving me any answers and amazon always giving them a refund without any involvement from me! It just seems so wrong!

Any help much appreciated. I know the courier one can be fixed by changing to one with liquids, but it's just too expensive.

Hi all, just cant get my head around this,, I have had a few customers lately who have purchased multiple copies of certain books in my inventory, yes i like the sale however take one example, customer buys three items same title, my postage charge nowadays mostlyL/L is £3.10, however the postage charge is divided into three, not really a problem however I have just tried to buy two identical items from a seller , and guess what trying to charge two lots of postage when both would easily go in one envelope, contacted the business seller who informed me cant do anything about this Amazon sets the postage charge, any ideas please
