Hi Greig,
Thanks so much for reaching out and for your interest in our products!
With Event Tickets Plus, you can set up discount codes right through WooCommerce by going to WooCommerce Settings<Coupons. Customers can then enter those discount codes at checkout when they purchase their tickets.
We are currently working on an extension that can attach PDF tickets to an email, which will be completed soon. For now, customers do get emails with their tickets once their order has been completed.
I hope this helps to answer your questions! Please let me know if anything else comes up!
Thanks,
Jaime
