shipping costs

Summary: du-885322 is starting out on eBay and is running into problems with shipping fees, even though they chose "buyer pays shipping" with Mondial Relay. Two sales went smoothly, but on the third, the postage was deducted from their sale, and in the fourth, the buyer chose tracked letter delivery, which was shown to them as free. du-885322 is looking for explanations and a solution to avoid paying for shipping twice. francexpressdeal suggests that tracked letter delivery was shown as free for a specific token.

Hello everyone,

I'm new to EBAY and I don't understand the shipping fees. I do select "shipping fees to be paid by the buyer" and I check MONDIAL RELAY every time, that's it.

The first 2 sales, no problem... the third: the shipping costs were deducted from my sale, and the fourth sale: the very honest buyer tells me that he saw the MONDIAL RELAY shipping costs as his responsibility, but that he

chose tracked letter and that it shows 0 shipping costs for him??

Can someone explain to me why it doesn't ask him to pay his shipping costs and, above all, how to fix this, because he has already paid for his order and I don't want to pay for the shipment once again.

Thanks in advance for your help
