Looking for local stores for Atari 2600 stuff (DE,PA,MD,NJ)

[mert]

I live in New Castle, Delaware. I hit only the local GoodWill's and Family Thrift. Anyone know and willing to share where some stores in lower Delaware, south eastern parts of Pennsylvania, north eartern parts of Maryland or southern parts of New Jersey that sell Atari 2600 stuff or any other systems close in age?
