Tortoises can be sold on here only when the selling rules have been met.
As for buying, we prefer you to buy from one of the forum breeders as most if not all start their hatchlings out the correct way.
We have "For Sale" and "Adoptions" sections here on the Forum, but to ensure that we don't turn into a classified forum such as Kingsnake.com or faunaclassified.com, we have a 100 post rule. New members must have contributed on at least 100 threads in order to be allowed to sell on the Forum.
