As I'm sure you know , Session Packs are an awesome way to sell multiple bookings all at once. You can read more about Session Packs HERE
Some Bosses want to offer their clients a reduced rate if the clients purchase a bundle of sessions. The way to do this is as follows:
In a session pack set your minimum and maximum number of sessions are the same number.
You will have see the option - "Show total price"
Check that and your package will show as a total price rather than price per session.
If you want the total amount to be less than you ordinarily price a session at- make sure to put in a lower rate in the price per session. Your clients won't see this- they will only see the total amount for that session pack.
Hope that helps!
