Just thought I'd let you know..
I went by my local Harbor Freight and checked to see if any blades had come in.. no, no blades.. .but the price on the slot where they go was now $1.99. So they have gone up $.50 already!
I expect there will be more price hikes before they are have them back regularily. oh boo..... Still.. $1.99 for two blades is a whole lot better than $5.99 for 1..
