About Cast Iron Canon

When retailers creep prices, we're watching.

Consumer-advocacy watchdog for repeat buys — water, detergent, ink, pet food, subscriptions. We track hikes and point you to smarter refills.

What we do here

We track retailer price hikes on the consumables people buy every month, name the increase specifically, and point readers to alternatives before they overpay. We do not take sponsorships from the retailers or brands we cover. We do not use affiliate links; the site is supported by the shops we run ourselves, which we label whenever we link to them.

How we pick

Every product on this site clears four bars before we recommend it: real-world evidence (rating, reviews, longevity), reasonable price for what you get, no concerning safety or quality issues, and at least one of us would buy it for someone we care about. We say no to a lot of things, including paid placements.

How we make money

We don’t use affiliate links. Some links go to shops run by the same team — they’re labeled. Those shops help keep the site free and independent. Read the full disclosure.

Who this is for

Cost-conscious consumers, budget-minded households, and anyone tired of watching routine purchases creep up in price without explanation.

What we’re not

We’re not doctors, lawyers, financial advisors, or licensed practitioners of anything. Nothing here is professional advice. If what we cover intersects with a decision that matters to your health or finances, please talk to someone qualified.
