The guy seems legit. I have him on my facebook. He had your lesser for $150 and he had a female lesser for like 280 right now. He had these nice prices on these lessers and when i hit him about about his pastels and ybs, i think he was charging a bit much vs going price for these hatchlings right now. Ive been seeing 800+grams male pastels and ybs goin for as low as $50 on craigslist in our area right now.
I LOVE craigslist! All my snakes are from craigslist actually. Ive gotten unbeatable deals! Bought my male pastel at 850 grams plus tank,heating pad and heat lamp for $50...hes breeding like a champ! All 5 of my females,all over 1300g, less than 100. And most recently i bought a "male" spider plus tank and accessories for $100 at almost 1000g...and turned out to be female!!! It dont get any better than that! I also got my 10 slot 28qt tub rack for $70. I work craigslist like a BOSS! lol
Also,your female isnt het though. No such thing as a het for lesser. Het means the animal is carrying a recessive gene,but lesser is co dom. Your female is just a normal female FROM the clutch your lesser was in.
