Alex For Easy Money and Easy Green plans, you can have up to 3 active physical cards without incurring additional monthly fees. Also, the first 3 physical cards that you order after first becoming a bunqer won't incur additional order costs if you're on these plans.
Btw I think it'd be a great idea to have choice between "just replace" and "replace and renew card" when ordering your replacement card. If I lose a card shortly after first getting it, then I might indeed want to continue with the same card number because of existing subscriptions, but if expiry date is only a short while away, not really worth it to produce a whole new card for such a short time span
