It didn't take me long at all. My son even has a card now, and he is diamond member as well. What I thought was nice - a while while ago I received this cheap paper looking card - but now they are issuing credit card thickness/feel to the C&A members. To get one of those, I just emailed them and they sent one out - I haven't had any problems with actually getting a number. I did have a great experience though - I am a member of
www.postcrssing.com and I ran into a girl that worked for C&A - she is no longer there (it's ashame) but she took real good care of me - it was so easy getting our son his number. She answered every little question I had about upgrades, their system upgrades and problems they have been having etc. It's always good to get the inside scoop.
