Hi Victor — thanks for writing in and I hope you had a great weekend!
Excellent question. It is possible to create another set of tickets at another price point that goes on sale at a specific date. That would allow you to set up a condition where one set of tickets goes off sale at one price where another set of tickets goes on sale at another price. I’ve used this personally to set up an Early Bird-priced ticket at a discount that expires on the same date that another higher-priced ticket goes on sale.
If you’re looking for something more automated and will be using WooCommerce as the ecommerce plugin, then you might consider the Dynamic Pricing extension for it. I think it’s mostly based on user roles, though, rather than time-based pricing. Still, could be worth checking out.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
