I bought 15 of the large cones of the Aurifil for piecing at the 50% sale last year. I won't have to be looking for a sale again for Aurifil. I did the same when the Ofa rotary blades were on sale for 60% from QIAD last year. I won't have to look for a sale again for blades for years. I always buy in bulk when there is a clearance price on the items I know I will be buying in the future. I have machine needles, thread, blades, scissors, seam rippers, pins, and clips to last me for many years. The price only goes up on these so buy them now. I can spend my money on new rulers and fabric instead of supplies.
