I placed a bid for something on January 18th. The auction is over tomorrow some time. On the 21st, the seller added a message to the auction that says: On Jan-21-09 at 13:13:17 PST, seller added the following information: SHIPPING MAY BE HIGHER THAN CALCULATOR READS. BUYER MUST PAY ALL SHIPPING COST. THE LAST BATCH I SHIPPED OUT COST $3.00 MORE THAN THE CALCULATOR READ. SORRY . Can a seller actually do that? Can you up the cost of an item after someone has bid on it when posted a different way? It doesn't seem right to me.
