Hmmm - I never got the email, & I know they have the email address as I remember putting it on the form when we rejoined at the NEC, & membership is active as had all the gubbins through - may give them a call to check they have it though - would hate to miss out on any UK site offers - especially the one you sometimes get which allows a friend to stay at members rates - really useful for the inlaws!!!
I have seen this elsewhere. I have only checked one European campsite as both the CC and the C&CC use the same site in Germany and by my reckoning the CC were just a little cheaper. Sometimes booking via one of the Clubs can be worthwhile if there has been a big shift in exchange rates. Personally tend not to book now but if you go in the main season it could be an advantage.
