Just found out about Jeff Kruys' problems in South America,
The shipping costs are outrageous -- hundreds of dollars ($500 Canadian) for a 5.1kg package.
Kruys is not the only one. A number of other long-distance touring cyclists have gotten stuck somewhere waiting for parts to arrive.
The arrival sometimes does not go as planned, either. Delays, wrong addresses or drop-off points, loss, theft, etc. -- a variety of things can and do go wrong between ordering and receiving parts.
Sean Grady was stuck in Mexico. Victor Weinreber also got stuck waiting for parts to arrive. (Will try to provide links to these later -- if anyone else knows of any links or experiences along these lines, please feel free to post them.)
There must be some better approaches or strategies for preventing these things from happening.
