i sold both of them!thx for the info i know your a big seller oveerthereIt will cost you anywhere from $18-$25 sending it through the post office. I would strongly suggest priority mail and of course you need to get insurance and delivery confirmation. It's very easy to send it through them.
Backing out of the agreement to sell the rod because you didn't know how much shipping cost really wouldn't be the right thing to do. If your old enough to post stuff for sale on an adult forum, then you need to be responsible for it. If you weren't sure about shipping you should have asked before pricing the item (like you did here) or done a search of the forum on bbc (there are tons of threads with this info). Not trying to sound like a d*ck but man up, fulfill your commitment and take it as a learning experience.
btw - If it was the BPS Crankin' Stick that you sold for $55 you should consider yourself lucky that you got that much. They only retail for $69 and are often on sale for $49. I'd get the thing shipped quickly and be happy.
