How this site makes money

Affiliate relationships

STEMkitFinder participates in affiliate programmes. When you click a link to a brand on this site and subscribe, we may receive a commission. This costs you nothing extra and does not change the price you pay.

This applies to ibrick, which is also our top-ranked recommendation. We think you should know both facts at the same time rather than discovering the second one later.

What commission does and does not change

Our rankings come from the weighting published on our methodology page, which was set before any commercial relationship and is applied identically to every brand. Commission does not adjust a score.

What commission does affect is which category a site like this chooses to cover at all, and how prominent the calls to action are. That is true of every affiliate site, and it is a reasonable thing for you to weigh. Our answer is to publish the scoring, name our bias on the front of the methodology page, and flag every place a competitor beats our pick.

Accuracy of product information

Prices, age ranges and product specifications are checked periodically but change without notice. Where we have not re-verified a figure recently, the page says so. Always confirm current pricing and terms on the brand's own site before subscribing. Educational claims made by brands are reported as brand claims, not as independently verified facts.

Questions

If anything here is unclear, or you spot something on the site that looks like an undisclosed commercial relationship, get in touch and we will correct it.
