I have bad news for you...
If you read in his item discription that shipping was $550, and it was posted on the auction BEFORE YOU BID, then you bid on an auction that was LEGIT to charge that amount. You cannot say after you have won an auction that you don't agree to the posted terms of that auction. Many people post excessive shipping fees in order to absorb the cost of the product...i.e. A cd on a dutch bid(of 100) that sells for a penny, but the shipping is $14.95 or so. It is a common practice, I have been E-baying for 3-4 years, and the one thing I have learned is read the info before you bid, and don't think if something seems funny it's a misprint, IT'S NOT! Why do you think it only sold for $2200, when they get $2800-$3000 all the time, and people bid on them like crazy! Do you think you were just lucky? I am sure others had read the discriptor, and unlike you, were adding that $550 into the cost, and they thought that $2750 was just too much. Now if he didn't post the fees, that's another thing, but in this case, I think you will have to cough up the dough. Sorry...
