I got a good deal on a new Xen helmet from Nashbar recently.
When it didn't arrive after a couple of weeks, I emailed them and asked why. [Apparently, my email filters had chopped their original reply.]
When asked why they hadn't sent the helmet, the lady answered...that the shipping cost to AU was $100 -00 US ! ! ! ! ! ... lol.. and they wanted to get the 'ok' from me before sending it.
[Normal shipping costs to me from the US is around $30-00 on a helmet.]
Nice .... lol.
I cancelled the order...heheheheh..
