What species do you want? Jacksons require much different temps and have to have them. Veileds like lower night temp drops but it is one of those things where they will not die if you can only get it down to 68 at night. Yes they would prefer 60 or maybe lower but they are hardier.
Honestly going to Petco and getting a veiled that just came in would be better then going with the place you mentioned and a few others that have them. You can actually see the baby and its size. See if it is alert with eyes open. But it is important to know how long they have had them. Under 2 weeks and you do not have to worry about over supplementation or mbd from back UVB lighting.
If you are looking into a jacksons now this is a great care sheet. And we have members here that have them... It might be a wait for one and they cost more then a Veiled but they are healthy captive hatched babies.
