Had to edit this post when I first made it because I included some faulty math; a minute ago I was redoing it in my head and realized I was working with the wrong can sizes; silly me forgot cans are 12-oz, not 20 like vending machine bottles.
So, retrying this...
Sale that local Safeway had the day I did all this: 2 12-packs for $11, or 3 2-litres for $6.
1 can = 12 oz 2 12-can packs = 288 oz $11 / 288 oz = 3.82 cents an ounce
1 2-litre bottle = 67.628 oz 3 2-litre bottles = 202.884 oz $6 / 202.884 oz = 2.96 cents an ounce
Even without factoring in the sale I already knew the bottles were the better deal; the price tags listed a "per pint" price on them as well, so even at non-sale prices it would have been more for the money.
