Apparently, it's true. Least that's what I've paid for in this year's Roayl Aeronautical Society (RAeS) subs.
Thought there was something wrong when I checked my bank balance yesterday and found it £257 short Turns out they've billed me for Fellow membership, and not Graduate/Associate membership, which is only £78.
All sorted out, thankfully, and by a person on a 'phone, and not some automated email/phone computer system, as is the case with most things these days
