As of October 2026 · 121 listings tracked across Amazon, Walmart & eBay
Prices change fast and stock disappears faster — YMMV.
Median across all 121 tracked listings: 4.4¢ per fl oz. The worst deal we saw ran 33¢ per fl oz — same product category, 30.0× the price per unit.
Best-value price is down 39.2% since last month — a good month to stock up.
Lowest we've ever tracked: 1.1¢ per fl oz (October 2026).
Once a month we pull live Sparkling Water 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.
