Whats the cheapest place to get eezoks?
It's Eezox. If you live in or near Washington County, Hafers sells it locally. http://www.hafersguns.com/
I don't know of any other place you can buy locally, but it's available online.
Edit: to answer the question, you may see cheaper prices online but that is before factoring in shipping costs, so again if you live within reasonable distance of Hafers it probably works out evenly.
