New general argument

Ik zal wel eens op de website gaan kijken. 

I have an even better proposal sir/madam, If you accept our exclusive offer you can use it immediately, you will receive our magazine, you can install the app and so much more. Would you decide that it's not for you after all, a simple phone call or e-mail and we won't send it anymore. This way you can immediately use this service and see if it can mean something to you. Would you like to comment on this?
