So... After going through 4 different stores I finally found one store in the Netherlands that still sells the big Monster Energy cans.
For the dutchies:
Albert Heijn isn't selling the big cans anymore.
EMTÉ says they never sold them.
Jumbo has them in some locations but not all of them.
Hoogvliet has them and they also have the yellow version eligible for the AC:Origins promotion. (Thanks W1998-rick)
The only cans I found with codes are the original green ones the other colors don't seem to have the codes.
The code is under the lip on top for anyone wondering.
