we can guess all we want, but what we know from the craigslist posting is that the seller is advertising that you "can sell it as your own".
certainly, this is pretty standard practice (unfortunately), but it doesn't indicate the most honest person on the planet.
unfortunately, the beekeeper that buys honey to "sell as their own" are the most vulnerable (along with their customers), as they never have the honey tested...larger buyers do. we've tested honey off the shelf labeled as coming from local beekeepers (even from "organic farms) that were 30% beet sugar....and no one believes that it was local to begin with. one beekeeper that bought this honey (from another country) certainly thought he was buying local honey to sell as local honey.....not imported honey that was 30% beet sugar. but of course, by the time he learns this, he's already gained the trust of customers with his "incredible honey"....he can't tell them that he bought it and didn't produce it...he can't tell them it is far less than pure...because they trusted him, and he has already lied to them (by saying he produced it).
wrt the cragslist posting, i have no idea who this is, where there honey comes from or what their businesss scruples are...but i'm wary that anyone that sells me something to resell and even suggests that i should lie to my customers about the origin could perhaps be a little fast and loose with the truth when talking to me about where they got it.
