GutKaufen is a free browser extension that turns your everyday online shopping into a charitable donation — at zero extra cost to you. When you visit a partner shop (like eBay, LEGO, AliExpress, Wolt, NordVPN and more), a small widget appears once per session. With one click, you activate an affiliate link. 90% of the commission we receive goes directly to charitable causes. No registration. No fees. No data collected. Just shop as you normally would — and do some good along the way.
