Actually I don't think it's that expensive.. and there are local companies that offer organic ethanol, as well as pure anhydrous ethanol.. but to order in bulk you have to have the alcohol handlers permit.. not looking to be able to sell alcohol for drinking, just to buy it for making tinctures, dewaxing etc..I think getting that permit will not be easy at all and cost you large $$$$ if you can even get it.
I think the wisest think to do is to get a still and refine your own from let's say Vodka.
If you can reclaim it afterwards you'll be so much better off than buying all the time.
