Hello, I wanted to respond to this question, it is a very good one. I have always let my credit card company know where and when we travel, what days we will be there etc. I think it is a good idea.
I live in Arkansas and Simmons Visa in located in Pine Bluff, AR. Maybe Simmons Visa keeps a closer eye on their Arkansas customers... one Christmas Simmons called me and asked me if I had made a particular charge at a store in Little Rock. (It was a large purchase at a store I don't normally shop at) I told them yes I bought it. Kinda of scary they know what you normally buy and where you normally buy it, buy if I had lost my credit card at Christmas that would have saved me some grief.
