I too have 10 pks on back order at my local HF and the manager said that he would sell them to me at the sale price of $1.49. He also handed me a 20% off coupon. Great guy.
But for those of you who do not have a HF near you I found that you can get 10 blades for $14.90. That is $1.49. Good deal at Jhittlesewing.com. You will have to pay S&H but still a good deal.
