Hey Bing,
Thanks for getting in touch with us and for your interest in our plugins 🙂
Unfortunately what you suggest is not possible with any feature of our plugins. But this might be possible using coupons from the e-commerce plugin you use in combination with our own ticketing plugin. Basically you can create this coupons and sell them as ‘gift cards’ or ‘event passes’, and then the user will use the coupon code at checkout for the discount to be applied. Does this makes sense to you?
For example if you use WooCommerce as the e-commerce platform in your site, you can use the Gift Cards for WooCommerce plugin to achieve what you are looking for.
Please let me know if this helps,
Best,
Nico
