If you ask me $8-$15 is more than fair for a single polyp for sure. I would also venture to say that $40-$60 would be a fair price range for a full 8 adult polyp frag (esp in the national market - and look at the price on our local market websites even). What you value yours with 3 adults and 5 smaller heads.........is up top you. Again the price is up to you and what you think its worth, like anything in this club you will quickly know if you are priced to high or fair based on how long the item lasts on the market
Never know what things are worth to people and just because it doesn't go in 15 minutes doesnt mean you have to give it away
* side note form the odd ball in left field - For instance I have zoas worth a few dollars and I would never buy a $500+ apex setup, alternatively I would buy a $400 vortech power head. Somethings people see value in and somethings not.
