A friend of mine in Indiana told me about Harbor Freight and we have one that is only about 25 minutes from our house. Never paid attention to the store. This same friend said that she thought they were actually cutting better than the Olfa blades. Since I have started using them, just a few weeks ago, I can attest to that--they just glide along and cut extremely good. I only bought one pack but plan to go back for more, if they have them.
