A membership is a recurring plan you subscribe to. You pay a set amount on a schedule and get whatever the plan includes.
Joining
Open the business profile or your account to see the plans available, choose one and confirm your payment details. It starts straight away. On the website the plans are on the business's page. Your account does not list Memberships.

What you get
It varies by business. A regular service included, a standing discount, priority booking or a free add-on each visit. What is included is shown before you subscribe.
Managing it
The website account lists Loyalty, Gift cards and Payment methods. It does not list Memberships. Ask the business if you need the renewal date or the price.
Keep your card current
A membership payment fails when a card expires. That usually means an awkward message rather than a quiet renewal. Update the card before it expires.

Common questions
When am I charged?
On the schedule shown when you subscribed, usually monthly from the day you joined.
Can I still book normally?
Yes. A membership sits alongside booking rather than replacing it.
Does a membership include everything?
Only what the plan says. Anything outside it is charged as usual.
