Club Magazine Crossword

Can somebody please tell me why the Caravan Club Magazine Editor has not taken care to ensure that the other side of the page that you have to cut out if you want to enter does not contain something that you may want to keep. It would not take a lot to have the other side containing a club advert, or even better the choice to enter on line similar to the MMM magazine, which the option of postal without taking out the page. This month for example page behind the crossword contains very useful information about fridge service which is worth saving so I have copied and added back to the magazine.
