The same Korean supermarket chain is selling lobster for $4.99 and $5.99 in the Mid-Atlantic. It sounds like it sells out fast on the weekend, though.

EDIT: So I was going to be in Philly tomorrow and thought I might try to pick up some cheap lobsters at the HMart in Upper Darby. My phone call to them was comical, however: I was literally transferred between 6 people, almost all with limited English skills, until somebody just hung up on me.

Me thinks the odds are low of getting lobsters there, but if you just show up, maybe it will work out.
