How we figure this out
Once a month we pull live Zero Soft Drink listings from Amazon, Walmart and eBay, read the honest quantity out of each one (fl ozs, in this case — the unit that actually matters), and divide the real price by it. Coupons that change what you'd pay today are applied; "subscribe & save" teasers are not. Then everything gets ranked by cost per fl oz, because a big box with a small number inside is still a small number.
