I do this too. Also, there is a place that I learned about here that you can send in your used blades and get a discount on new blades. They sell both Olfa and generic blades. Their prices were really really reasonable. I'll see if I can find the name.

If you exchange 5 blades, and they don't have to be olfa, you can get new olfa blades for $3 each, minimum order of 5 and free shipping. Seems like a steal to me!
