I’m old enough to remember Tab and Diet Pepsi in the old school 12 & 8 oz. glass bottles, and in vending machines (‘70s). Seem to remember them a little cheaper, and a 2 cent or 5 cent deposit on the bottle too!
16 oz refundable deposit bottles. I remember seeing 6 packs on sale for less than $1, but the deposit was maybe 10 cents a bottle.
Also stubby bottles, some with styrofoam labels.
