I've got all mine setup so the instant a purchase happens i get alerts. So far I haven't ever been breached ..but it still comes in handy - for example last week I was getting charged $795 instead of $7.95 for a beer hahaha. I actually request new card numbers every year or so too.

Must have been a really terrific beer at that price {g}. I like the idea of changing card numbers every year or so. Thanks for the idea.
