I used to buy 99% IPA from Amazon or ebay, for maybe $20/gallon USD. I need to re-up my supply and am seeing price increases everywhere. Typically $30/gallon or more and the sellers I used to buy from aren't selling gallons or they're selling 4 quarts at a higher price.
Just curious where you're getting the best prices for IPA and other chemicals. I'm in the USA, but also curious if prices are rising elsewhere.
