Do you have to order it through the Waywell website via telephone or email? I don't see an option to buy it from the site...
I emailed them at the general contact email address listed on their website and told them I needed it shipped to the USA and that I wanted to pay via Paypal. If you don't already have iGo8, then you may want to opt for the extra $5 SD card with the mapping software pre-installed.
You should get a response from them with the total and proper Paypal address to send money to.
Better yet, I have a gently used Witson T720V that's currently for sale... (Kidding)
