I think the deposit must be new.
Haven’t read all the reviews on here, but I’d be suprised if anyone paid it.
I seem to recall someone posted they got abuse for cancelling? So perhaps they are using deposit to ensure numbers. I think that will backfire and they won’t get enough numbers to make it worthwhile for them. Could be a cheap way to get an FFFM but I expect they will then cancel at short notice, and then you need to get back your deposit.
Nah stick to organising MMMF with reliable regulars.
