$8 a polyp isn't actually that bad for a lot of the zoanthids out there.
Candy Apple Reds usually go for around $20 per polyp.
Although if the ones they have at your LFS are just some generic zoanthid that is a big ridiculous.
Are they just common zoas or "named" ones that look REALLY nice, like RPPE or lunar eclipse or fire/ice, etc?
I am in Pennsylvania and would be able to provide you with smaller frags of around 3 or 4 heads of each type of zoa you want.
Although I only have "collectors" zoas so they wouldn't be like $2 a polyp or anything.
If your interested you can PM me or send an email.
