I'll be calling in an order for knee pucks this week and wanted to know if anyone else is interested (save on shipping). I'll be getting two pairs of these for $20 each. http://stores.sportbiketrackgear.com/Detail.bok?no=375 If we get enough orders to spend $150, shipping will be free. Any orders at all will reduce the shipping that we each have to pay. Let me know by Wednesday as I need to get these for the Labor Day track day in Utah.
