I noticed this special as you have and thought the price was fair if the corals are in good health. I have no experience with Jeff's; bu, I will tell you that I paid $5 for one shroom and another $5 for one ricordia frag from a individual, if this helps you in judging the value.
If you do take advantage of this offer, please give us some feedback. The deal sounds terrific.
