Ever since I've got my 2nd fraudulant charges in 2 years on my cc that I use for ecig related stuff only. I buy all ecig related stuff using one CC and buy nothing else on that CC. I check almost every day the activity on that CC. If I see anything suspicious I notify the CC company and resolve the charges. I've done this for the past 3 months, I haven't lost a penny with the fraud, my cc company has covered me on both instances, cancelled the old card and gave me a new card. I do have fraud insurance on the card though that costs me $3/month but it's worth it. I use Paypal whenever I can, mostly for generic hardware (batteries etc) here in the USA. I use Paypal when buying ecig stuff oversees (ecig hardware and eliquid). I have found myself buying ecig related stuff more often overseas, since they almost always accept Paypal oversees.
You don't need the fraud insurance. Honestly.
