There is another spot in NJ that is actually on the way to the others, closer to the GWB than Fish Hut and Absolutely Fish. It's small, but I have found things there that helped. They do have some plants as well.

Also, you can haggle at Absolutely Fish so long as the price doesn't have "net" written next to it.
And Rt. 4 Aquarium gives a 15% discount to TPT members. And Mike will get you anything he can so long as you ask for it. He has hooked me up several times with stock that he normally doesn't keep.
