I'm building a shop where registered users can attend activities. They can bring in 1 other person, but for that person the price is a bit higher.
I was thinking about a product variation: like a checkbox if you want to book for 1 extra person. And then they pay the normal price + an extra fee.
But when they choose that option, the general stock must be lowered with 2! Because 2 people attend.
Is this possible? Or any tips?
(I tried a bulk pricing plugin, but it's not suited for this situation.)
