Affiliate disclosure

Short version: some links on FitCheck may earn us a commission when you buy something. It never changes the price you pay, and it never changes which products we list, how they're sorted, or what the price history shows.

How we make money

• Affiliate links. When we're approved by a shop's affiliate program, links to that shop carry a tracking tag. If you buy after clicking, the shop may pay us a percentage of the sale.
• Sponsorships. Accessory brands may sponsor the newsletter or a clearly labelled spot on the site. Sponsored placements are always marked "Sponsored".

Where things stand today

As of Oct 19, 2026, FitCheck has no active affiliate or sponsorship agreements. Shop links are plain product links. This page will list each program we join, as we join it.

What we promise

• We list every product we crawl from a shop, not just the ones that pay.
• Price history is what we recorded – never edited, back-filled or estimated. "All-time low" means the lowest price we have recorded since we started tracking that product.
• "Compare at" prices come from the shop and are labelled as the shop's own claim.
• Fitment is extracted automatically and can be wrong. Low-confidence matches are marked "needs check". Always confirm with the shop.
