incorporating workshop waivers at the time of payment and clients pay for paypal fees

[Mermaidshining]

Hello everyone,

Presently I'm developing a website via GODADDY and it has paypal as payment source for workshops.

Is there a way to incorporate a "workshop waiver clause" in paypal for attendees to sign off on just prior to payment?

Is there a feature for attendees to pay for fees when purchasing a ticket just as they do on 3rd party ticketing venues such as eventbrite?

Thank you,
