They are based out of florida so that explains some of the prices. Stuff like ricordias, some zoas, and a lot of snails/crabs are all local. I know of several GOOD reliable places out of florida. Their prices are super low since its locally collected stuff and one place has free overnight anywhere in florida.
Not backing this place, no affiliation, never heard of them. Just stating their prices are in line with some other smallish outfits in florida.
EDIT: sorry, thought 757 was tampa, but no its 727. 757 is norfolk, Va. No clue why this place is so cheap.. haha
