How MightBuy makes money
Last updated: 18 July 2026.
The short version
MightBuy is free. When you click out from your shop to a retailer and buy something, the retailer may pay us a small commission. The price you pay is exactly the same either way. That's the whole model: no ads, no selling your data.
How affiliate links work here
When you click a saved product in the MightBuy web app, we may route that click through an affiliate network so the retailer knows the visit came from MightBuy. If you then buy, the retailer pays us a commission out of their own margin, typically 3 to 10% of the sale.
We plan to work with established affiliate networks and retailer programmes. We'll keep this page current as they go live.
Our rules (what we will never do)
Trust is the whole point of a tool like this, so we hold ourselves to a few firm rules. These are design principles, not small print. The product is built so we couldn't break them quietly even if we wanted to:
- Links only become affiliate links when you click them in the MightBuy web app. Nothing happens silently or in the background.
- The browser extension never touches your links.It captures the product page's address exactly as-is and does not add, modify, or replace any affiliate codes, links, or cookies.
- We never interfere at checkout.No injecting codes, no swapping tracking cookies, no claiming credit for a purchase we didn't genuinely refer.
- Commission never affects what you pay or which products we show you. Your shop is your shop.
Prices can go stale
The price shown on a saved item is the price we captured when you saved it. Retailers change prices constantly, so the live price on the retailer's site is the one that counts. We're not the seller, and every purchase is between you and the retailer.
Where you'll see disclosures
This page is the plain-English disclosure, and it's linked from the footer of every page. On top of that:
- The browser extension's store listing and interface will disclose our affiliate participation, as required by the Chrome Web Store's affiliate-ads policy.
- Shared wishlist pages (/s/…) will carry their own inline “links may earn MightBuy a commission” note for visitors once affiliate links go live.
