Connecting Threads has great prices on the precuts. Also, if you sign up for Quiltshops.com's mailing list, you can get all sorts of great ads. The shops vary, but I've gotten some great deals (example Tonga Treats for $19 - over $40 in my LQS). When you see a sale, they do sell out quickly, so if you want something, you have to be quick to order.
