When this first came out, I went online and ordered 2. Harbor freight sent me an email and told me, I had to order at least 10 dollars worth before they would ship. DH told me to order 10 packages which I did. At the time they were 1.49 a package, I had to wait almost 2 mths, because of all the back order. They did send cards out, and if you wanted to cancel your order, you sent the card back. I did not want to cancel my order so I did not send the card back. Be careful if your waiting for your order and get a card in the mail to read it twice. I know of someone who sent the card back not realizing they were not suppose to.
