IMO, and talking with actual owners of LFS, they make their livelihood from non-exotic stuff, cheap every day stuff, dry goods (that don't die and don't require electricity to keep alive), those sorts of things.
There might be a few exceptions to the rule, but it would be a hard time running a high-end coral only store.
At this point, you might as well run the business out of your garage (save renting a place), do online sales (open yourself to the rest of the world), and allow locals to pick up or something.
