Hello Reid

Thank you for your purchase.

Unfortunately, at the moment we don't have a bulk purchase option. Our developers are currently working on adding that feature, but until then I can offer a work-around.

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.

Another way of doing this would be through recurring events, or recurring appointments. If you go for the recurring appointments, you would need to choose in which manner the appointments will recur, and for how long; but that still leaves your customers to choice. Meaning, they would still be able to book individual Appointments, or they would be able to choose less weeks than what you intended to do.
