I usually see members posting them for sale for around $75-$100 PP. Towards the lower end for multiples and more for frags with a low number of polyps.
I'm not sure if they are selling at those prices but thats what I normally see people asking for them.
I get $100-120 for mine easy but I have the clientele to sell to for that price being a well known seller and nationally known with excellent seller feedback.
