My Harbor Freight store is sold out and they can't say when they'll be getting any more in. When the website shows they have them and not on backorder then the stores will have them again. I'll keeep an eye on the website before I make another trip to the store(they get weekly shipments from their warehouses).

I finally found them. For the price you can't beat that. No wonder they are on backorder. What size are these?

I just found the blades on line at Harbor Freight...They are so cheap, but the shipping is 6.99. But even with that I paid 11.60 for 6 blades plus shipping. You still can't beat it. They are on backorder, but it is worth the wait.

Did you check if they had other shipping options. A lot of the sites do, usually a little drop down arrow beside it.

I saw someone else post that their shipping was only $4 something.

I guess the quilters in my area haven't found this yet, or they're all out of town for the summer! The HF near me had about 20 packages! I was good & only bought 3. :-)

I ordered yesterday. I know it said backorder, but, I can wait. They sent me an email with an order number, and it says that when the order is ready to ship, they will send it. I did not make an account with them before I ordered so I can't trace it or anything as it does not show up when I did make an account.
Luckily, I do have a confirmation of the order from them

When you find a great price on rotary blades by enough to last you for years! About 10 years ago I found an Ebay seller that bought surplus from a warehouse and he was selling the blades 144 per box! He had no real idea how they were used in quilting, concentrating more on the saw blades he had to sell. I bought two boxes and paid $30 per box. Now I could kick myself for not buying more but back then that was a lot for me to spend on blades. LOL.

What size are these blades?

They are 45 mm and they come two to a pack.

Check with flooring stores that installs carpet, they can order the carpet cutting blades cheap too.
