No I didn't got the Quidco offer...

It is not that I can't spend less than 1k pounds per month, of course and I can but I have to buy some things for my mother/sister which are expensive (2K each item)and as you can understand I really want to buy those through my AMEX card and not from my Debit. I will follow your advice and before try to buy them I will call AMEX to give me permission for those, now I just received my Girlfriend's supplementary card and I will ask them if I can send them also her's financial details so that they can raise this limit again.
