I bought two "golfball size" Chaeto algae from the eBay seller "exterminatank". I paid $18 for this, shipping included. The algae arrived from NY to CA in 5 days. That part was good. The amount of algae I received was really the amount for what I would consider one order. I have asked the seller to refund one of the orders or send more. I'll keep you updated on what happens.
