These guys (well actually, 2 guys and a girl) came in with the feeder shipment at petsmart.
Anyone have any idea what they are?

If there are guys can we see their parts? Then an ID attempt can be made. Otherwise it's pretty much guessing from a suite of crayfishes typically found with ghost shrimp.

A few more and you could have a meal! I'm guessing they are either Lunch or Dinner.

I am guessing they are derived from a bait fish farm in the midwest or northeastern U.S. and were impurities within a bag of fathead minnows (possibly rosy-reds), golden shiners or goldfish.
Based on rostrum which barely be made out it is an Orconectes sp.. Based on coloration and overall appearance, especially the chelae, it is not O. rusticus (illegal for trade in most states now) or O. propinquis. I am guesing it is most likely O. immunis or light colored O. virilis. CLoser look at rostrum would distinguish. Strongest case for needing good visual of gonopods, in my opinion, is if critters are not O. immunis. Both O. immunis and O. virilis frequently found in bait fish production ponds in midwest and former in northeast.
