Jennifer Garner -- Two Can Play That Ring Game (PHOTO)

Jennifer Garner and Ben Affleck are in lockstep on at least one thing -- their wedding rings stay in the picture ... for now.

Garner was out running errands in Atlanta today, and still sporting her wedding band -- just like Ben was a couple of days ago ... also in Atlanta.

All you romantics should NOT get your hopes up though. Our sources say Ben and Jen are simply committed to co-parenting their kids, and part of that includes wearing the rings around them.
