Basis

Unit prices on Loblaws, No Frills, Walmart.ca. One unit, in place. No tracking. Reports are opt-in.

Canadian grocery sites print unit prices in mixed units — $/100g, $/kg, ¢/100g, $/lb. Basis rewrites that line on the page so comparable packaged items use the same unit. The shelf price does not change. Cards sold by each (no mass or volume) are left alone. Tested on Superstore, Walmart.ca, and Metro. Built for Loblaws-family banners, Voilà, Amazon.ca, and other named Canadian grocery hosts. Choose 100 g, kg, or lb for mass; 100 ml or L for volume. Private by design. Parsing runs on the page. No account, no ads, no affiliates, no tracking. A problem report is opt-in: the popup copies hostname and rewrite counts to your clipboard and opens a blank GitHub form. Turn it on from the toolbar when you want it.
