How cheap? Bourbon whisky and what brand. I do the same occasionally and tonight is one of those nights. Military Special out of the Class VI on post. About $16.00 a half gallon or so.
Usually in the 4-year Beam, Early Times, Heaven Hill, Seagram's 7, Canadian Mist variety. I'm primarily a bourbon guy but have experience with other whiskys as well. Lol.
Cheapest I ever had was Kentucky Tavern, $2.99 for a fifth in 2001. You could see stuff floating in it.
Happy drinking to you, warrior.
