Hi Lucy,
Thanks for your interest in our products and for reaching out to us!
Hopefully you can add up as many tickets ‘types’ as you need for each event, there’s no limit on that ๐
Regarding the coupons, that’s something tied to the E-commerce platform and it’s settings. For example: our product WooCommerce Tickets works with WooCommerce, basically when you create a Ticket for an Event, the plugin creates a WooCommerce product and relates it with the Event. So once you add the ticket to the cart the e-commerce platform manages it as a normal purchase. You should be able to use coupons without any hassle.
I just set up a quick test to double-check on this. I can confirm this works as expected with WooCommerce Tickets + WooCommerce.
Please let me know if this answers your questions,
Best,
Nico
