For quite some time, the KDE e.V. – KDE’s non-profit organization – is listed in the AmazonSmile program. On the AmazonSmile website it says:
AmazonSmile is a website operated by Amazon that lets customers enjoy the same wide selection of products, […]. The difference is that when customers shop on AmazonSmile (smile.amazon.com), the AmazonSmile Foundation will donate 0.5% of the price of eligible purchases to the charitable organizations selected by customers.
In other words, if you do a lot of shopping on Amazon anyways, make sure to start shopping via smile.amazon.de and choose the “KDE e.V.” as organization. This way you financially support the KDE e.V., even without having to pay more. I am posting this here since I know many people who buy things on Amazon several times a week. Feel free to spread the word & happy shopping :-)
PS: This is not supposed to be advertisement for Amazon. You can also donate to the KDE e.V. directly.
PPS: It seems the KDE e.V. is only available on German Amazon.
