A FlexBooker package allows you to combine multiple appointments into a single item that you can then sell. For example, "5 Guitar Lessons" or "10 Hour Long Massages"
Packages are separate from the regular services, so can have a different price than the services that are assigned to them. For example, "6 Sessions for the price of 5"
Packages can be assigned to all services, or only to specific ones. If they are assigned to specific services, they can only be used when clients are booking those certain services.
