I went to harbor freight's websiste, ordered 3 packages of the carpet cutter rotary blades, and with shipping, I got 3 packs of 2 or under 8 dollars. That's better than Joann's half off. I priced thier 60 mm replacement blades this weekend, 5 blades $50.00. With the price of gasoline, the 2.99 shipping was cheaper than driving to one of their stores. I just copied and pasted your name and number , googled it. ordered it and was done.
