Waiting for my Form 2, I figured it was a good time to get some IPA. Searched around for gallon and five gallon quantities to get a decent price. Formlabs recommends 90% or better.
I was surprised to find 91% isopropyl alcohol at Walgreens for
$2.29 per 16 ounces. But it happens to be buy one get one for 50% off. Then, if you buy enough it ships free. I put 22 bottles in my cart and checked out for $38.46 shipped.
That is $13.99/gallon for 2.75 gallons. No need to leave your house or get strange looks buying 22 bottles of IPA.
