There is an awesome store just south of Boston called Uncle Ned's Fish Factory. All sorts of rare fish, incredible wild cichlids, plecos, catfish, just an awesome place. Coincidentally I was in there last night and saw a fresh batch of healthy looking Pandas come in. I'm pretty sure they do ship as I think I saw it on their website once. Not sure about costs though. Check them out though! Been going there for several years.
goodluck!
