Hi Kistie. I did a quick check at ebay and the best price for the 45mm blades, that you don't have to bid on, were $12.95 + $2.25 for shipping for 5 blades. That's $15.20 or $3.04 per blade. They are $3.00 per blade from LP Sharp and what I like almost as much as the price is that I can recycle the old blades with them. Again, my ebay search was really quick so there may be a better price there. Don't have much time to do a thorough search because I need to walk the dog and get ready to go bowling. :lol:
