Hello Charlie

Thank you for your purchase.

Unfortunately, at the moment we don't have bulk purchase option, but it is being developed. It should be included in the plugin in the next month or two.

You can create a service which would be named "Bulk Purchase" for example, and it would cost a certain amount. Then, you would need to create a 100% discount coupon which could be used 9 times, and limit the usage to 9 per customer, like this:

My advice would also be to enable the notifications, so they get an e-mail with the discount coupon, explaining that they need to use the coupon for the remaining 9 sessions:

You would need to add the %coupon_1% placeholder to the e-mail, so they get the coupon code they can use.

After someone books the first appointment, they receive an e-mail with it, and they use it to book the remaining 9 sessions.

I hope this helps.
