Never owned or intend to own a credit card..
I have switch Maestro which is accepted almost everywhere really for online purchase and shops.
My moto has been "if you aint got it then dont spend it" but i do understand the use for one, it's just i've never ever needed or want one to evert start with
Good though within 5 or 9 mins they were on phone to you, wow! Makes a change
My grnadfather had his card stolen and they were drawing thusands of pounds out everyweek. He didnt get one phonecall to ask why and he was 80.
It finished him off
