Scenario we are wishing to do:
A family wants to buy a gym membership. One person will use his/her credit card to buy it as a package. But up to four people might use the membership and we need name, phone, and DOB for all of them, but without cluttering up the checkout page.
This is a new strategy for us - up until now we've been forcing each person to go through the checkout process individually even if they wanted to buy as a couple.
What would you suggest as the best way to do this?
