Ours also offer a form of discounted membership to those who require long term buggy use because of medical issues. I can’t tell you the cost, but anecdotally I have heard it’s a reasonable saving.
I know of members that have agreed discounts for regular buggy hire and the club runs a scheme where if you have one regularly you get one free every so often.
The majority of regular buggy users have their own one. Which makes financial sense. My buggy cost £3K which is about the equivalent of about 18 months buggy hire.
