We have some events with a minimum price and would like to add the feature of a free gift ammount. For example I will book one ticket but as any extra I would like to pay more for the concert. How can I manage any extra options for my customer above the booking and let them pay this in the checkoput. ?
Anyone a suggestion ? I would like something like a bonusfee of 1 euro witch the customer can add in the checkout and can set to one ore x euro's
