I can buy grain alcohol that’s 95% pure alcohol at my local liquor store. It might be kept behind the counter where I have to ask for it, but it is available.
Grain alcohol is illegal in many states. California restricts alcohol to 60%, for example, so you won't be able to find it in any corporate place, though you can occasionally luck out and find a bottle in a small liquor store that doesn't mind selling pseudo-legal things.
