I suppose I fall into the category of “garage farmer” (although my systems are in a spare bedroom) so I’ll offer my thoughts on this subject. While you are correct in that I don’t incur the same expense of a brick and mortar, I don’t think you’re considering how much work and other expenses go into operating even a small coral propagation operation. Even one as small as mine. Most weeks, I dedicate at least 20 hours of my time to growing corals and I spend roughly $350 per month to run the tanks. Should I not be compensated for that?
Offering completely free shipping is simply unrealistic and wouldn’t make sense for ANYONE to do. I sell the majority of my stuff for <$50. By your logic, I should lose money to ship you a frag. As much as I enjoy aquaculture, that’s not going to happen.
FWIW, over the last two decades I have purchased corals from pretty much all of the biggest and most highly regarded vendors. I’m not kicking them, they are fine. However, the best corals tend to come from the smaller operations and fellow hobbyists. The prices tend to be far better as well. This hobby 100% needs guys like me, or else it would be far more expensive than it already is, and that $50 shipping charge would be a welcomed annoyance.
