Group-Buy Discount
Pick your first card at the normal price — anywhere from €15 to €35 depending on the design. After that, every additional card you add to the same order is only €5, no matter which design you pick.
The discount shows up automatically in the order form as you add cards. No codes, no coupons, nothing to remember.
Works well for mates ordering together, hen parties, stag dos, birthdays — basically any time more than one person wants a card. One person places the order, adds everyone's cards, and you split the cost between yourselves.
