I sent my DH to get me the blades. He asked for the blades, and they pointed him to the power blade wall. He came home after walking through the store, and not finding them. 2 weeks later I happened to be driving by, and stopped. They pointed me to the power blades. I just kept walking through the store, and lo and behold I found the the carpet cutter with 2 blades, but they were out of refill blades. I bought the whole thing as it was cheaper than 1 blade at Joann's or LQS. I'm going to try going on line. Oh, by the way, they work just great.
