Bride markets may seem outdated, but they're profitable for girls' families. And they're controversial.
Some reports say for one Orthodox Christian clan in Bulgaria, a bride can cost as much as $5,000. Even though there are price negotiations, the nomadic group doesn't consider the practice as selling girls.
The girls often won't continue their education after they are married.
The group doesn't allow dating before marriage or dating outside the group. Part of this is because they're often marginalized in Bulgaria and Europe.
So a market may be the only chance to secure a suitor or bride.
