Christopher I looked on Dutch and German Amazon local help websites, but nowhere does it mention that Maestro cards are accepted. While Thijs is correct that often Maestro cards aren't meant for online payments, the bunq Maestro cards actually do work online at the few number of sites that accept Maestro online payments. It's a rare sight to behold, however. And Amazon does explicitly not accept them.
But just to give a real-life counter-example: DLGamer does accept Maestro payments.
