I wouldn't say Bol.com is a good alternative to Amazon as their terms towards sellers is quite toxic, but I also wouldn't know any other alternative either.

Bol.com has been infested with drop shippers using ai, try searching for "aanpassing titel" lol. Besides, because of their "free shipping", most products are actually more expensive because they have the shipping price included, and you can buy it for less directly from the seller's own website.
