About the same thing happened to me too! About a year ago, 2 weeks before I was supposed to leave the country, I just randomly checked my bank account and there was a $500 dollar purchase from NewEgg on it... luckily I caught it the day of the purchase and was able to cancel it, but man.. such a pain, I had to cancel my card, use a temporary card in a different country, and have them send me a new card all the way across the world.
By the way I'm from AZ too

luckily I moved 2 weeks ago though and I'm definitely not missing the heat! Haha. But I heard you guys had a pretty big Habuub recently though >.>
