Well no wonder. Those guys are even farther west than we are.

You're paying INTERNATIONAL rates.
They're not the only game in town. Check out Currie Industries or TNC Scooters. They have all you'd need at reasonable prices and shipping rates. Btw, some of these places only advertise UPS shipping. You gotta ask if they can ship via USPS instead. One company told me no problemo going with USPS Priority instead of UPS. Big difference shipping out this way. Also, take advantage of USPS Priority Flat Rates as well. If you order small stuff that can fit in the PFR boxes, you only pay around $8 up to around 50 lbs. Good to keep in mind when ordering, say, motors or SLA battery packs.
