As with what alexinfla said, the price for a pink is highly dependent upon the variety of pink. I can tell you in my system, we have three different varieties of pinks, and one I wouldn't spend more than $15 on the 20+ polyps I got. On the other hand, one of the varieties, I probably would have spent $10/polyp on, but fortunately I didnt, my girlfriend picked it up as a browned out colony that colored up very nicely for cheap.
It really is like any other zoanthid, there is no real "right" price, especially if you cant post a picture. That being said, the price is also highly dependent upon where you are and where you are selling to. Different areas of the country, heck even different cities in my own state, get different prices for different things, simply because in certain areas, the supply of that particular coral is limited.
