About Cardmarket Optimizer

I always felt like the website cardmarket.com makes ordering your cards more expensive than necessary, so I created this tool as a hobby project. This app saves you real money, mostly by bundling cheap items at low delivery costs. It works by applying techniques from optimization science (that's my day job). The plugin is very easy to use: just select your wants-list and go through the wizard! If something doesn't really work, or if some feature could really be handy, let me know! I am happy to reply and would like to make the app as useful as possible. Works for all Cardmarket games: Magic the Gathering, Pokémon, Riftbound and more!
