Here's what happened, I won an auction on ebay with a best offer. The seller then sent me an invoice with with my best offer but the shipping price was more than it was on the actual auction. He made up for the amount he lost in the accepting my best offer. I emailed him asking why the shipping price was now higher, he said it was a mistake and I should only have to pay the $4.95 priority shipping price. I tried to pay him with paypal but it keeps coming up with the inflated mailing price. I asked him to send me a 2nd invoice with the correct shipping price he said he couldn't. He said I should send him what's on the invoice and he will return the rest to me. He has 100% feedback but that isn't saying much, right now this seems really fishy. My question for sellers is can you only send 1 invoice? ebay doesn't let you send a second invoice? Is this guy lying?
