The pack-size trapThe biggest pack we tracked (676.3 fl oz) looks like the bulk play, but it runs 1.9¢ per fl oz — the 68.2 fl oz pick wins at 1.7¢ per fl oz. Bigger isn't automatically cheaper.

How we figure this out
Once a month we pull live 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.
Our Amazon links are plain links — no affiliate tag, no commission.
Amazon doesn't allow affiliate sites to run price alerts, so we chose the alerts. If eBay or Walmart links ever earn us a commission, they'll be labeled (paid link) — and it never changes the price you pay.
