Just to clear this up a little bit more, I went through the complete history of my card (October 2014-now), it is as good as all Paypal or Amazon except for two purchases on a famous German website in December and my recent 3.50 USD transaction here. In my case my bank did not block the transaction and I am 505  Euro out of pocket at this stage and although you do not store info on your site, the encryption process might have been hacked into. I am also not pointing fingers but same as my bank, I am highly suspicious. For me this now means filling in forms and eventually even having to go to the Police fraud department. I should have known better after the fiasco with the other site where I was also part of the lucky ones!  Please don't brush this off...It might not be at your end, but it could be since I don't appear to be alone here....and 'no', I never had any issues here before and I felt safe, thus I used my card this 'once', which makes me really annoyed with myself....I am from Luxembourg.
