I purchased a Het albino from Eden Reptiles and was very pleased, I purchased him and he arrived perfectly. I would definitely recommend them as they have very good prices.

I purchased my pastel from Wicked Pythons and once again received very good service, communication, and the product was perfect. I would recommend them because they also have great prices, and if something is a little high for you they allow payment plans.

Lastly is LLL Reptiles. They are very good because, well I dont think I have to explain because they are one of the best companies out there. They have a pretty good name in the reptile industry. So I would definitely recommend them.
