A lot of times (from what I have experienced so far..) is if you call the breeder and have a good conversation with he or she, if they have the time, a lot of times they will take a bit off and include the shipping. It never hurts after getting to know the person/business just to ask how firm they are on their prices.
Some are as is, and some are willing to work with you. A lot of breeder's can also do payment plans for you. If you stick with the big timer's you are:
1. Guaranteed top quality animals
2. A pleasant and hassle free buying experience
3. A chance to B.S. with someone about snakes (who usually knows a hell ova lot more then I do so u get a chance to possibly learn a thing or two)
4. Possible flexibility and/or payment plans.
5. Chance to build a relationship with them for future purchases.
Hope this helps! And like I said above.. none of these are guarantees, but every experience I have had with the big dog's have been an extremely positive experience. Never hurts to ask and Good luck!
