Waiting for my beverage at Starbucks, I received an alert from Amex - 'card not present on my additional card member's account'. DD has had my card for years and rarely uses it because she has two Amex CCs herself.
Charge was from LivingSocial and after verifying with her, I contacted Amex. Apparently, there was a $1 charge from PayPal today -guess testing the account. Amex is overnighting her replacement card and blocking the card from charges.
I checked her history and she has used the card 4 times this year and only once since September. I have to assume our impromptu trip to Trader Joe's on Christmas Eve was the culprit; if I am wrong, I will apologize profusely.
Moral of the story, make sure you sign up for text /email alerts and monitor your accounts.
Ill certainly be watching. Thanks for sharing this.

Just curious if there was some breach or something I didn't hear about. Trader Joe's was the first place I stopped when I got off the plane on Christmas Eve, needed to stock up on wine for family time...
I can't be sure, she hasn't used her card since Sept and that was the only place it has been used. This card isn't linked to any online shopping profiles because she has her own card.
Again, I am basing it purely on usage and her infrequent usage of the card.

And you never paid me back the $200 I lent you
LOL.
