Buying 2 BP's..need ur opinion
Well, normal baby balls go up to 80$ at pet stores, if I recall correctly. You should seperate them unless you're going to breed them. If you buy them you might want to get them both to a vet check. They're probably fine, but the vet can make sure they don't have any parasites of any kind.
I'm not sure how much an adult normal female would go for these days, but it's probably over 100$. You could probably breed them now, but it would really depend on the weight and how healthy these guys are.
Are you sure they are male and female? It'd be good to know for sure before you try to breed them.
