Based on what is less money. Item for item SWF.com is cheaper that purchasing from my LFS. But the difference is I don't have to spend a min of $75 dollars. I can purchase any amount worth at a time from LFS. But if you want several thigs at a time, I think you'll find it cheaper in the long run to purchase from SWF.com. Being somewhat thrifty as my wife puts it, my $75 cleanup crew I just purchased, would have cost about $97 from my LFS. Explaing this to my wife allowed me to add $20 worth of coral to my tank. Also remember that purchasing is smaller lots from other sites as well as this one, you must include about $30 for freight charges. That's another pc of coral or crew if you want it. HTH
