and learned to knit socks. NYS Sheep and Wool Festival in 39 days!I am dusting off credit card once again.(insert wicked evil laughter here) I had a similar experience a few years ago. It seems that my normal purchasing patterns trigger fraud alarms. I will go for 2 or 3 or even more months hardly charging anything at all & then charge a ton in a few days. This was especially true when my daughter lived 1,000 miles away & I would try to visit her 3 or 4 times a year. And, I confess, falling down in LYS from the yarn fumes may have been involved on a few occasions. But fortunately, Citibank called me before denying any of the charges. But a few weeks ago, I went to an Ulta 3 to buy some makeup & toiletries & the charge (same card) was denied. Like you, I do not carry a balance on my cards [that interest buys yarn instead 8-)]. I was so pissed (it's embarrassing to have all the other customers think you're a deadbeat who doesn't pay her bills) that I called Citibank on my cell phone right there while the clerk was ringing up the transaction on my American Express. CB explained that they had had a security breach (which I take to mean that someone broke into their computer system) which involved only some of their accounts (my other CB account was unaffected). So they closed all those accounts & issued new cards.
