It's not the credit card you need to be scared of. It's you.
We are a debt civilisation, if we can't afford it, we borrow so that we can. It's a sad state of affairs but such is life. The "devil" is our mentality of buy now, pay.... whenever we feel like it.
IF you think you can be regimented enough to pay it all back on time and before it builds up then go for it. If you cannot, then wait, save, and maybe, just maybe you might get them on a deal a bit further down the line.
