I don't use eBay check out - and only use USPS shipping and insurance (optional). HOWEVER, I'll be pleased as punch to speak with eBay about the problem. I love speaking with them. most of the time I get a useful person. But then and again I get the one that still hasn't figured out the keyboard let alone eBay. I love to torture them with the obvious question and then watch them stumble around. Seriously, I'll go and chat with live help and add my concern to the problem with shipping calc.
