Hi @Ray Carnes,
But when I use the pricelist to define a discount on Event tickets based on the number of tickets, I get an warning message "A pricelist item with a positive min. quantity cannot be applied to this event tickets product."
Do you know how to fix it?
Thanks,
Pedro

We don't support Min. Quantity for Event Tickets. The main reason is consistency of how pricing has worked over the last several versions. There are also implications on having different "tiers" or "levels" of tickets linked to the same product. If you have a Gold, Silver and Bronze level tickets, and you give a discount when more than 10 tickets are purchased - does this mean 10 overall?, because Silver and Bronze are probably already discounted, and you could buy 9 Bronze tickets to get a discount on the more expensive Gold ticket that you may or may not want the etc. You would need to customize the code to support this.
