I put KLM in the Google search field and didn´t pay attention and clicked KIWI. These days, Google doesn´t list the site one wishes to access but to sites that pay them. And it cost me dearly. I booked a KLM flight from Amsterdam to Vienna and soon thereafter discovered that it was 25% more expensive than if booked via KLM. I immediately contacted KIWI but they refused to cancel the reservation and refund me. So, be aware, they will rip you off.
