Thank you fraud protection

I get a call this morning from my bank to call then immediately regarding my credit card. I usually have a good memory of what transactions I make so all of the sudden I start backtracking all of my activity. I confirm with one of the reps of my purchases until she mentions a $5,600 transaction to some website called collegesportsnetwork.com. I quickly confirmed with the rep that I didn't make that type of purchase. I look back years ago when I got that card that I actually was going to waive that protection. Sure it only costs a couple of dollars, but it beats having a bill I'll probably lose sleep over fighting. An old colleague once told me he's never done his finances via internet. I thought he was crazy with what technology we have now, but after what happened, I saw what he was getting at. I probably would cry if I saw what took me eight years to build destroyed.
