I just discovered that google is launching their "paypal/amazon/ebay" service:
express.google.com
The good thing is that they offer 20% off on the first order, and they team up with some online skateshop.
Through this "express" thing, I have ordered Bones Race bearings from Action Board Shop, and got 20% off, no tax and free shipping, and it took 3 days to come from Michigan to California. If you want to get a nice discount on costly bearings or trucks, it's pretty interesting !
The offer ends 10/31.
