Do those beers have a puzzle inside the cap?
I remember buying brew 102 for $2.09 a 12 pack. it was almost like non-alcoholic beer, you'd get full and get a headache before you ever got drunk.
Not cheap, but a couple of years ago someone gave me two six packs of Spaten. I almost gagged one down, ended up pouring the rest of em down the drain. For me to do that you know it must have been rotten putrid bitter garbage. but I'm sure someone with a "sophisticated" pallet will tell me it's good tho.
