I read on here that someone got blades from ebay--so I looked and bid on some, lost that one, but got the next deal!! 30 Olfa 45mm blades for $1.97 each--including shipping!!! I just bought 5 for $30--(with 40% off) at Joannes... so these are 2/3 off the regular price. These should last 3-4 years!! :D
