sorry but I have to laugh out loud, Your bike is a Jap bike, not a Harley or a Buell, that means it ain't made in the US of A, and like most aftermarket parts these days they all come via China. as you dont live in China, you have to pay shipping, its called the Global Economy.
try living somewhere like Australia and then have a whinge about shipping and parts availability or the lack thereof..
sheesh some people's expectations.
So just going to say there are plenty of screens available for the GSXS, just not many that come with free shipping!
Just for your info about what the rest of the world pays, T-Rex Sliders posted from Texas to Sydney Australia, USD$160.00 (that equals $220 Aussie Koala's just on postage) that's the same price as the parts.....
