I started using virtual credit cards. I use a free service and have multiple cards. I use one card for ebay. when I make a purchase I change the limit on the card from $0 to the amount I need, make the purchase and then turn the card back to $0. I use another one for Netlfix, the netflix card only allows 1 transaction a month of no more than $15. I use them for trail memberships too. They are linked to my credit card which I have fraud protection on that too. I like this as my CC info is not being used all over the net. Sometimes it is a pain to login change the allowed amount and then go and change it back to $0 afterward. The nice thing is using it for free trails, no more forgetting to cancel before XX amount of days or getting overbilled by a company.
