so 140 for the 4 snakes total? What are the ages and sex? Who is the guy your buying from, is his story legit? Did he raise/breed them himself? 140$ for 4 young (<year old) females sounds normal. And also, I dont want to hassle you at all, but is a few grand going to cover everything? You may be able to buy property for that small amount, but can you pay for the bills out of that???
Maybe it's the market I'm around. This isn't a huge economy in MI, but the land alone would cost well into 100,000's, most likely more. And the cost for license, taxes, utilities, merchandise, and animals, along with necessary health costs. I would persoanlly shoot for 200,000's if I could. But I guess I dont know that much about the biz. :/
