Once a month we pull live Mustard 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.

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.
