I'm pretty sure that you are not on the line for Credit Card purchases.
However my GF had her Debit Card stolen, which isn't as "safe" as a Credit Card. Someone was buying gas at a gas station everyday for a week. Clearly passing the card around amongst freinds.
Anyway yeah just do everything in your power. My mom had someone buying Jewelery in Europe once with her CC info
