Lets make this more impersonal and not directed at any one person.
Baby sulcatas need to be kept warm all the time. They are sensitive to low temperatures. Even a few hours of too cool temps can set them back, make them sick, and shut them down. This can happen in a pet shop or in a new keepers home. To give an example: I left the power off to my adult sulcatas night house one night and temps that are normally around 80 dropped dow to the low 50's. Not a big deal. Adult sulcatas can survive those temps, but its still not "good" for them. They didn't eat and were very lethargic for four days after that. Babies are much more sensitive than adults to these things.
In any case, read this BEFORE getting another one: http://www.tortoiseforum.org/threads/hatchling-failure-syndrome.23493/
It will explain what goes wrong and what questions to ask. Most people still start sulcata babies all wrong. Now that you have your enclosure and temperatures all squared away, I would hate for you to run into the typical chronic dehydration related problems that so many people encounter. If this seller does not know the answers to these question or if they tell you these hatchlings were soaked once a week and kept on rabbit pellets, cut your losses and find a breeder who starts them correctly. It is not worth the hearth ache of doing everything "right" spending hundreds or thousands on vet bills and having the baby die anyway. Just spend the money for a baby that's been warm and well hydrated since day one.
