This discussion has been hashed over a hundred different times. There are people on both sides of the fence as far as pricing in concerned. I for one can see both sides of the arguement, however, in this case in particular I did a little research as I am in fact looking for a lesser something to add to my collection.
I do not think the snakes this man is selling are poor quality. Actually they look a lot better than some of the snakes I have seen for higher prices. His BOI on Fauna is all good reviews, so he doesn't have a bad reputation in that regard. If it is a quality animal he's selling at a price he believes is fair, then so be it.
He may be doing so because he's getting ready for new hatchies, maybe he had 30 pastel lessers, there are many reasons a person might reduce pricing... everyone seems so quick to jump on the bandwagon to wave their pitch forks at people that sell for less than market value. I think if they ever found themselves in a situation where they needed to move some snakes or earn some money quickly, they might not be so quick to judge.
