The main reason I have one is for hiring cars when I go to Spain.
Using it for online shopping too could be the future.
I had a bad experience in Australia with hiring a car with a credit card off Hertz. It was hired at Sydney airport and dropped off at Cairns Airport where there was no one to receive it and just a box on the Hertz reception desk for the keys.
When I got home I got an invoice for the hire which said the car had been damaged (which it hadn't) and my credit card would be charged the £300 excess on the insurance I took out with the hire. They'd taken my credit card details when I picked the car up so they could do that automatically.
I tried to get in touch but if you look on the Hertz web site it's very hard to find out where you go to complain. I eventually found that their customer services desk is in Ireland and contacted them and they eventually sorted it out but it had me sweating on 300 quid for a while.
Dead dodgy giving out your credit card details and that was with a reputable global company like Hertz.
