My Discover Card calls me every time I charge over $100. I’m very grateful. I always call each discover card I have (one for gas and one for incidentals) tell them I’m going to Florida or wherever and all gas charges on the 1-95 corridor are ok and any one night stay in hotel in the south is OK. This year, I forgot to tell them that I’d be fishing and any charter charges would be OK. I got a call that they wanted to know if the two $800 charges were legit.? I really believe they are looking out for me, but I could be wrong.
It isn’t a good idea to tell strangers you’ll be away from home. That’s an invitation for a break-in.
