Re:Faygo Uptown - too pooped to participate.
Our local IGA store sells 20oz FAYGO soda in it's cheapie soda refrig. Usually 2/$1.00. Several flavors-Cola, Root Beer, RedPop, Peach, PUNCH, and Grape. I have noticed they tend to be pretty flat when opened. I recall RedPop being quite fizzy when I bought it many years ago.
