I bought mine from HSN when they first came out. I have since sold the Go cutter but kept my dies to use in a Sizzix cutter. The best prices I have found for dies is J. Hittle Sewing supply. They have free shipping on orders over 100.00 in the lower 48. They offer so many other items it is not a problem to spend 100.00! I got several of the basic dies for less than 19.00 each. The strip dies are expensive no matter where you buy but I paid only 55.00 each for mine when I bought them a couple years ago.
