Yes I did know of them CC my daughter had some with her Christening gift monies and hubby has a friend who is very luck with his.
Not saying I am 'that' rich but -
It's a good idea, not something I have ever thought of TBH, have had money in investmentments for years but the interest has been lousy hasn't it. Best one I have had was several years ago when on advice I put some monies into a kickout plan - that did quite well considering the interest rate.
At the moment mine will probably be worth much more if I died as it has a 'death payment' linked to it.
Food for thought - cheers
ps we will get you into parliament
