I went by my local Harbor Freight last week for a tool box for my daughter, but thought I'd check on the blades while there. My store sells them 2 for $1.99. They had about 20 packages on the rack and I picked up 8 packages. When I got to the checkout, the clerk good-naturedly said, "You didn't clean us out of these did you?" I told her, "No, I left quite a few." She then said, "Those things sell so fast. As soon as we get a shipment in, they're all gone!" So, I asked her if she knew why they were so popular, to which she replied, "QUILTERS!!!" I just had to laugh.
