Can I buy from a salesperson or with their link?

The organizer's salespeople sell tickets on site for cash. After you pay, the QR codes of the tickets appear on their phone right away: take a photo, or give them your email address and you also get them by email.

You can buy from them online too: if you open the event with the salesperson's link, their code is added to the coupon field automatically. If the code comes with a discount, the price drops right away.
