The coupon code is SAVE10. It works at this site which seems to already have low prices. Plus they offer free shipping on all orders.
It used to be on the home page, I don't see it on the site anymore but I just tried it and it still works. You just enter the code during checkout on the checkout page in a field called "coupon code" and it takes the 10% off right away.
Fastin Coupon Code: SAVE10 will save you 10% on any order plus Free shipping for fastin.
