GBtortoises said:100% definitely a Chinese Box turtle, Cistoclemmys (Cuora) flavomarginata.
$100 isn't a bad price. "Perfect" adults of the species go for $125 & up nowadays. they are absolutely awesome Box turtles to own. At one time years ago I had about a half dozen of them along with some other Asian and American Box turtle species and the Chinese Box were hands down my favorite. They're very active, love to burrow and like lots of water.
Below is a photo of some that were born at my place back when I had them.
It's amazing to me how much they are nowadays, about 15 years ago they were anywhere from $7-15 each!
