Here is my question. On hatching egg auctions, there is a shipping cost. So if it says, $12.50 and you pay the $12.50, then recieve the eggs and the boxs shows that the seller has only paid $5.55, how do you handle that??? That's almost $7.00 difference. I have only bought eggs twice, so I do not "know the rule". Is this just how it is done? Would you contact the seller?
