I have been buying from a store called Cutters Creek

mainly because the prices are great for members and shipping is free if you buy $10 or more. Anyway they have SCAL (sure cuts a lot) boxed version on sale for members for $55.99 which is a great deal.
I am not sure if you can use a coupon with software but you can try KIMSFRIENDS and save another $5
BTW, it takes 24-48 hours aqfter you register to become a member, you will know that you have been on the list when you see 2 prices, the regular nonmember price and a cheaper members only price.
