Come to the LIRA meeting -- I will bring 3 or 4 bags containing both Caulerpa taxifolia and C. serrulata for the auction. I think at the last meeting they went for around 3 or 4 bucks a bag.
Or... if you don't make the meeting, and you'd like to take a trip to Hicksville, you can come to my house and I'll give you some.
