I get Kona at Hancock's of Paducah for 3.98 a yard, but have seen lower prices posted from time to time
AccuQuiltGo is listed at Amazon.com for 218.00 (seller is Fabric Hut) and at Sew Vac Direct for 199.99 (they have good deals on other stuff, too)
Check "best price" retailers at nextag.com for just about anything
