What's the best way to buy one of these gasses without having it delivered? I saw some people in the thread saying going to certain stores, can anyone enlighten me?
@hellocana Welding stores carry industrial gases for welding and other applications, such as brewing. Looking up welding stores near youis a good place to start. When you find one, you can call ahead and ask what sizes and what purity of nitrogen (or Argon or Helium, if you go that route) they have. You're looking for >99% purity for any of these gases, at least 40 cubic feet. If they ask what it's for, you can say it's for nitro brew coffee.
