Congrats guys! I really enjoyed AA's suggestions and comments regarding the site - I really wish to implement some of those ideas. It was also cool to have a 3d software related discussion with Marcin.
Anyways send me a message with info what your webstore accounts are and I'll add you to Supremes so you could benefit from a discount. Remember that atm it works only with full checkout, with regular PayPal - PayPal Express won't work (hopefully by the end of the next week it will be ok).
How it works? Simple - make your orders usual way. When you go to checkout you should see your discount on the order total :) .
