Thanks for your answers @Azure and others. Looking forward to improvement on the shipping like others. Its a little sade to make a modular laptop , and the first day you need a module you cannot do it because it sooo expensive ! It kills a little part of the thing…for now 
3€ is the real price with shipping 
Just ordered it will see.
It has one regular usb C + one for charging. Exactely what I need!

Ho yeah, I don t know much about logisitc. But I know the guys at geek buying (where I bought some stuff) they have a whearouse in Poland…and when you order sometimes its in poland sometimes its from china. It comes by train or something, you wait 3 weeks,…BUT its CHEAP 
On a psychological perspective I would prefer to buy the SAME USB C module 20€ and have 8€ shipping…which would end up 50€. But I would have the feeling I have not been robed for the shipping (compared to other comon sites prices.) This is sneake markzting I don t like , but real 
Finally during the ordering process of my laptop , I would have liked a message :
" You have choosed only 3 MODULES we highly recommand you take at least 4. Ordering more will cost extra 30€ shipping costs! " Or setup by default 4 usb c… explaining somehow this is the standard…because when you have the choice , you feel like “hey this is the concept , let s order some more later”.
