Thanks. I was only visiting sites with secure connections so I was a little perplexed.

When the unauthorized transactions happened, I was mostly pumping gas at Mobil/Exxon to take advantage of their reward/points system. I eventually stopped because of those damn skimmers. I started using the app to pay and collect points, which is easier, anyway.

I have since switched to pumping at Costco exclusively again but now that means I have to go back to swiping my damn card. I'm going to get a new debit card soon and only use my Citi Costco card at the pump. I read skimmers are more sophisticated now and can't really be detected. ;-(

Unfortunately, my local Costco stores don't have the pay fob option yet.
