Thanks for making me feel better .
I am livid. Received the 'bumf' in post this morning. Sent email to school midday. Was 'invited' to speak to head at hometime.
Seems I am only person to have ever raised the issue with them and they have participated in the 'competition' before.
Schools all over the UK have been entering these 'competitions' for a few years now (wonder how many ask permission of parents first]. This one has a closing date of 30th March yet seems 'winners' are already being notified.
They 'didn't think anything of being asked to include dob/home address, yet agreed, when asked, that normally it would only be the schools details and child's name given in all other types of competition. They took advice from 'the department' before speaking to me and said they will make sure it doesn't happen again, albeit seemed not to quite understand why I was annoyed.
I asked if the school gained anything but it seems not (other than one copy of the book), by the way to buy one on the special offer would be over £15 including postage.
Eldest confirmed my suspicions about motive behind competition by saying all the class 'won' and a good number from other classes did too.
Have sent email to education department on return home. Await their comments.
Changed name to sillymummyornot as was starting to wonder if I was (silly) and why so many other parents don't seem bothered. OK I don't have to subscribe to magazine or buy the book but hey, it is certainly a wonderful marketing technique by the company to get a great mailing list..and many will feel obliged to buy as they are proud of their son/daughter.
Felt so let down by school but at least they will do something about it (but have probably marked my card as 'awkward mum').
