I use Paypal it is just that wee bit too easy, one click and its spent.
I had a T/C from my bank the other day saying they were concerned about possible misuse of my credit card. After frantically checking my card accounts were OK, I rang the bank and it turned out to be a holiday balance I was expecting.
What had happened was that they had automatically stopped a payment as the payment code or what ever it was had flagged it up as a catalogue company request and it was a lot more money than it would normally be for a catalogue purchase.
I was rather impressed that the Banks automatic "alarm" system had flagged this up.
