I generate free virtual cards with the Capital One Eno chrome browser extension Works great and you can set a date for it to lock itself after to block charges, they even suggest it as a use case for stopping trials from charging you, etc. It generates a card per website and you can replace it as many times as you want all for free. Anyone else using this awesome service?
