That sounds similar to what I am doing. I have a ticket type for one price = 1 registration and another ticket type for a different price = 2 registrations and so on. I would also like this on the wishlist for future development.
@Frederic Ozon has paid for developing this feature. I will see if I can come up with a solution to include this into the extension (so far, only few customers need it). Maybe to make it less confusing, we will add a parameter into the plugin to allow turning it on/off and have it off by default
Will inform you when it's implemented and ready to use
So I have the code implemented as part of the core package. Before I merge the code to main release, do you want to help me to test it? If Yes, please submit a support ticket so that I can send the package for you for testing
Just for information, this feature will be disabled by default. You have to set Enable Weight parameter in the plugin to Yes to enable this feature
