Yes, can you buy and book a single lesson or workshop, but all purchases must be done from the 'STORE' page (not from the 'BOOKING' page, which is for use only only if you have sufficient store credits – which you purchase in the 'STORE' – to book a session).
To pay for your single lesson, select the 'Book & Pay' tab from the menu at the top of the 'STORE' page. Then choose the type of lesson you want to buy ('Individual', 'Group'*, 30-minute, 1-hour, etc.) from among the different sessions available.
Once you have made your payment, you will be able to choose the day and date of your lesson or workshop and book your appointment.
*Note that new individual (without a 'Trial lesson') and group lessons and workshops bookings need to be approved before the booking is accepted.
