I went to Harbor Freight to check and see if they have the carpet cutter blades. And yes they did. I only bought myself 2 packages. Soon as I can I am going to go and get some more. Anyways, I ask the girl at the checkout counter if its something that they always have in stock and she checked and said "yes we always have them in stock, in fact there are 30 packages in the back and what is on the shelf" Well what was on the shelf had to be at least 40 or 50 packages!!! But there was a ton of them. Just wanted to let you know that the Harbor Freight that is nearest me (an hours drive away one way) has a ton of them. :)
