Question: is it cheaper to buy 2 liters or cans?
Answer: If we look at the 2 liter bottle of soda, at the name-brand price, its usually $1.29, again with no sale price. ... This is equal to about 5 and a half cans of soda, which then levels out to about 23 cents per 12 ounces of soda! We save approximately 10 cents per 12 ounces of soda when we buy 2 liter bottles of soda.
