The pack-size trapThe biggest pack we tracked (36 oz) looks like the bulk play, but it runs 28¢ per oz — the 5.5 oz pick wins at 16¢ per oz. Bigger isn't automatically cheaper.
Median across all 121 tracked listings: $1.22 per oz. The worst deal we saw ran $7.13 per oz — same product category, 44.6× the price per unit.

How we figure this out
Once a month we pull live Toothpaste listings from Amazon, Walmart and eBay, read the honest quantity out of each one (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 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.
