I am in Ontario and we have 7 Len's Mills stores in Southern Ontario. Their Olfa blades are $6 but their Komfort Kut blades (distributed by H.A. Kidd) and Tailorform Replacement blade (distributed by Symak Sales) which fit Olfa cutters are $2.99 and once in awhile are on sale for $2 which is when I buy at least a dozen. I sharpen each blade at least three times with my Orbitol sharpener (not as good as new but not bad). Last month I found Fiskars blades 60 mm on for $2.99 too. I don't think Len's Mills stores are in the west but you might be able to find the other two brands of blades I mentioned and they are a lot less than Olfa blades.
