I made rag pillows for Christmas, and I can testify to the fact that the cost of the GO and the dies was well worth not having to cut out all those fringes! I would have been getting surgery on my poor hands LOL.
With regard to finding dies on sale, Nancy's Notions also has good prices. I bought my GO with a bunch of added dies on Overstock.com for a pretty good price also. They sometimes have individual dies for sale, and their $2.95 flat rate shipping can't be beat - well, unless they have a free shipping promotion, which is quite frequent.
