Where we earn, and where we don’t.
Valumech participates in the Amazon Associates program. That means a small number of links on the site are affiliate links, and if you buy through one we may earn a commission — at no extra cost to you. Here is exactly where those links are, and the firewall that keeps them away from our numbers.
As of 23 August 2026 — we update this page as our affiliate relationships change.
The required statement
As an Amazon Associate, Valumech earns from qualifying purchases.
Where the affiliate links actually are
We only add an Amazon price link to a robot that is genuinelybuyable on Amazon. Most robots we track aren’t sold there at all, so they carry no affiliate link. Every active Amazon link must match a specific model and configuration on a live product-detail page. Lookalikes, accessories, unavailable products, and search-only matches are excluded. When a model does have a link, it is labeled plainly as an Amazon option and sits alongside — never in place of — the maker-direct price.
Valumech does not copy Amazon prices into its catalog. Amazon prices and availability change frequently, and Amazon requires live price displays to come from its approved Creators API or Product Advertising API. Until that integration is configured, the Amazon button sends you to the current product page to see the live Amazon price while Valumech continues to show independently sourced manufacturer pricing.
It never touches the numbers
This is the important part. Affiliate status neveraffects how models are ranked, how their prices are recorded, or how their used values are estimated. We don’t reorder the catalog to push affiliate products, and we don’t inflate or discount an estimate because a link earns. The commission exists to help fund the work; it has no say in the editorial. That separation is written down in our editorial policy.
“Visit maker” links are not paid
The “Visit maker” links that point to a manufacturer’s own site or store are plain reference links — not affiliate links, not sponsored, and not paid for by anyone. No maker pays to appear on Valumech or to be linked from it.
