well, they accept paypal and paypal will gaurantee the purchase if not you can get your money back. But if you're gonna buy anything like this, try to find it on the major motorcycle websites instead.
www.bikebandit.com,
www.denniskirk.com, cruisercuztomizing.com, www.j&pcycles.com. Now, I will say this, they may not be the cheapest compared to knock off sites, but there is no risk on purchase. I'm sure some others will chime in.
