Affiliate disclosure

Effective Nov 13, 2026. Written to be clear and conspicuous under the FTC's Endorsement Guides, 16 CFR 255.

Affiliate applications are pending. Today, store buttons go directly to the retailer and we do not earn a commission on those clicks. After Amazon Associates, Impact (Walmart, Target, Best Buy), Sovrn Commerce, or eBay Partner Network approve us, some of those same buttons will become affiliate links. When that happens, this page and the short note next to each button will say so. We will not pretend a plain link is already an affiliate link.

The material connection

A material connection exists when we can be paid because you used our link. That payment is a commission from a retailer or an affiliate network, not a higher price charged to you. If you prefer not to support ProvePrice this way, search for the product on the retailer's site without using our link.

Where we disclose it

  • A short disclosure appears immediately next to every outbound store button.
  • A site-wide disclosure appears in the footer of every page.
  • This page is the full disclosure, linked from both of the above.
  • Social and Telegram posts that include a store or site link will include a clear disclosure such as “#ad” or “affiliate links.”

A footer-only or “legal” disclosure is not enough on its own. That is why the short note sits next to the button you actually click.

What money does not buy

  • Commissions never change a truth score, a verdict, or the order of deals.
  • We do not sell paid placement in the catalog.
  • We do not use a browser extension or cookie-stuffing to attach an affiliate cookie without a click.
  • Costco product links are never affiliate links. Costco has no product affiliate program.
  • Sam's Club product links are never affiliate links on this site, because that program's terms conflict with price tracking and alerts — which we also do not offer.

Programs we are applying to

We plan to apply to Amazon Associates, an Impact.com account for Walmart, Target, and Best Buy, Sovrn Commerce, and eBay Partner Network. Those applications are not approved as of Nov 13, 2026. Tracking IDs, when issued, are pasted into a single config file (src/affiliates.json) and are not hard-coded into product URLs.

Amazon and Sam's Club limits

Amazon Associates policy restricts site-level price tracking and price-drop alerts, and limits how long catalog prices may be cached (24 hours). Sam's Club Creator terms likewise prohibit price tracking and alerts on Sam's Club products. ProvePrice does not offer price-drop alerts for any store. Amazon prices older than 24 hours are not displayed as cached prices.
