Be sure to sign up for their emails. You will get notices of the sales and most of the time, the designs are 1.39 each. When browsing, I usually just put the designs I like on my "wish list" and then when there is a sale, I can look and see if any of my "wishes" are on sale. Did you check out their tutorials? great information there as well.
I have also found that their designs stitch out wonderfully. Never had a problem with any of them.
