I'm getting so tired of these. It seems like every few months now I'm getting affected by one. Last year my bank replaced my debit card three times (Adobe breach, Target breach, and who knows what the third one was)! Consequently, I'm no longer using my debit card as a debit card, but only at ATMs. I use my credit card for any card-based purchases now. But it doesn't stop. You name it: zappos breach, dropbox breach, a breach at an old community college I attended years ago, and probably others that I've forgotten about in the last year or two. Fuck me running.
By the way, the stories about this breach claim that no financial data was compromised. That's fine, except that the data that was compromised may be used for identity theft: your name, date of birth, and street address. I'm pretty much getting ready to use the option that the credit reporting agencies offer to lock down my credit so that no one can obtain credit in my name without me unlocking it. It's a pain, but I don't think it's a choice anymore at the rate these breaches are going.
One thing I've done for a while now is use Citicards' Virtual Account Number service for any online credit card purchases. It generates a unique number that can be used one time (sorta - if the purchase has multiple stages like Amazon does for example, the retailer can place several charges) by one retailer. It's a bit of trouble, but I don't have to concern myself that a compromise at one business will cause me to have to replace the card. Plus, if a compromise ever happens, it'll be immediately apparent which retailer is to blame.
