Sure they're a bit higher...an 8-pack of 7.5 ounce costs about $3.00 while a 24-pack of 12 ounce costs around 6 bucks
So why would I "waste" money on the 7.5 ounce?
2 reasons
1. I almost rarely am thirsty enough to drink a whole 12 ounce can immediately....I drink half to 2/3 of it and the rest sits there until its flat and has to be poured down the drain whilst a 7.5 ounce can is the perfect amount of fresh beverage I want
2. The most delicious taste in the soft drink world is the first couple drinks of a freshly opened can....after being exposed to air and just sitting there opened it begins to quickly go flat thus if you only drink half the can the rest is gonna taste like watered down garbage by the time you get to it
If my fellow degenerates want a nice change from drinking flat watered down cans try the 7.5 ounce cans...they might be 9 bucks for a 24-pack instead of 6 but you wont regret it!
