Do a search online for Rotary Cutter blades on sale. I do that for most quilting notions I need. I find the most amazing sales sometimes. About a year ago I found on the search a warehouse place was having an inventory sell out. I called to check on the blades and got free shipping. I got Gingher rotary blades, five to a package for $4.99 a package. I got 20 packages. I think Ginger isn't making them anymore, the person I talked to said they were probably going to be rebranded so out with the old packaging. ? Anyway I have saved a lot of money by stocking up when I had the chance.
