I have an electronic subscription to the NY Times. I get unlimited viewing on computer and mobile device. I do not have the upgraded plan which gives premium access to some of the more popular columnists. It costs $15/month. Worth it in my opinion. I can log on from anywhere, from work, home, or on the road. If I had a print subscription it would cost more and be less green.
NY Times charges your credit card once a month for the service. This week I got a message from AmEx: on Sunday, there was a suspicious string of charges at stores I never use (WALMART) so they froze the card. My card had never been used at WalMart, so the fact that someone wanted to buy $492 from WalMart triggered their software to decline the transaction. I bought gas on Sunday and I'll bet someone skimmed the card information by inserting a reader into the gas pump after I made my purchase.
I have been issued a new card with a changed account number. One word to the wise: if you have recurring monthly charges (such as a NY Times subscription), be sure to change the payment info so you don't have declined charges. Likewise, for any online retailer where you have "securely" stored your credit card info, go in and change the account number.
With respect to online payment of the credit card bill, AmEx said that payments sent using the old account number would be credited (i.e. they can accept payments for the old number, even though it is frozen for making purchases), but of course you would want to change the acct number programmed into your bank's online payment website asap. However, had I made an online payment two days ago, unaware that there had been fraud activity, the payment would have been credited properly. I checked the AmEx website. They already have my new acct number displayed, and it shows purchases made with the old number. The new card will be delivered today via UPS.
