The card thing is a wank, I have two mangers who work for me who utilise them to pay bills accumulate points etc as part of their salary package, they will always work for me, as this is how they roll, sacrificing lifestyle for cash, all fees and charges are a drawing of their salary,me I would take the most cash on offer save, and get out on my own, but im happy for the deal, whilst they are high maintenance employees they are also very good at what they do and I am very happy for them to always spend more than they earn.
The secret to being able to get credit without cards is to own shit, save then buy something of value with a preference to finding something that doesnt depreciate in value quickly, once you are in the positive position your credit will be fine, only a dumb ass would look to build up a rating by accumulating debt with high interest on cards to improve their rating, do the hard yards first up get your rating.
