This weekend i sold the last of some special ink cartridges and the buyer was to pay shipping. After the auction ended the buyer paid 46.36 in shipping + the item. When I went to print out the shipping label my cost was $63.34 - $7.00 for buying shipping thru PayPal/eBay so my actual shipping cost was 56.36. But that's $10.00 more than what he paid. Did I do something wrong? I have sold these in the past at smaller lots and this was the last of what I had. So it's the same ad I just relist it for the next auction. It's hard to be upset about this when the item is all profit as I got them free. Just don't want this to happen in the future.

Thanks
