Yikes! $15!! Sorry to hear that, perkussion.
I do so hate when the shipping costs more than SEVEN times the cost of the item you are ordering!!!
Some places (I can't say about the 'numbers' place) will ship some small items by USPS first class mail for a much lower rate,
IF you call or email and request it before placing the order.
You could also try this site. Just type parts, or Grand Vista, or whatever in the box on the left and select Kymco in the drop-down menu. I don't know if you'll have much luck with it this time of year, but ya never know.
