Problem with seller on Ebay, what do you think?

[ossman99]

I bid and won a 71-72 grille surround on ebay, seller outlaw_josey, looked like a real nice used peice. seller had listed in his add 24.95 shipping, so i bid it up to 177.50. seller sends me an invoice charging me 75.00 to ship it. contacted sell he stated he made a mistake on the shipping and was like sorry either pay it or he would relist it. i offerd to pay half the actual shipping witch was 87.00. he flat out refused. Am i wrong for being a little pissed or sould i have paid him? I understand mistakes happen but the shipping greatly influenced what my top bid was.
