Cheng As I said above, you can look up on the homepage what features and cards etc. are included with your plan and what would come in as an extra.
In case of the Easy Money plan, you have 3 physical cards of your choice and 25 DigiCards (virtual cards) included with the monthly price. That means if I understood you right and you have now ordered one physical Mastercard and one physical Maestro card, then that is still fully included with your plan and doesn't come at an extra cost.
All of this is detailed on https://www.bunq.com/benefits if you look at the column for the Easy Money plan. If anything is unclear, then just ask :)
