I have been buying my blades for the past year from HF. I signed up for their on-line flyer and get a "head's up" when the blades will be on sale. I then order then on-line and they get her quite quickly. Have only had 1 out the the ones I've used be a little wonky. I love it. My sewing budget wouldn't stand the price of them every where else. I occasionally stick a pkg of 2 of them in my SP boxes. Always buy 10 sets a a time. Sara
