How are you going to ship a bike for $10.00 or even $20.00! That will be like $100.00 of more, (if you take it apart would be a little less). if not much more to ship!!! You may want to put just local pick up and tell the bidder your very sorry, Trust me that will be very costly to ship.
I have had this in my watch list for days and I don't thing the shipping will be that bad I won an apple mac G5 that weighed about 35 pounds and shipping was right at 29 dollars, still it's a nice bike and worth the shipping cost to the winner.
