I agree, hes young, into the hobby and volunteering HIS time. No matter what, you got a nice mushroom, you like it and thats all that matters. Some people have access to cheap corals, I recently paid 15 for 3 lavender mushrooms but have seen red tongas for 15 a polyp it all depends on your location, and availability of corals. If there is only one store in 15-20 miles they can pretty much charge what they feel like.
