Kid Ink -- My Vegas Arrest Was a Bargain

Getting arrested in a Las Vegas nightclub probably SAVED rapper Kid Ink big money -- 'cause he just paid a measly $120 to make the whole mess go away.

As we first told you -- Ink was arrested for disturbing the peace at 1OAK nightclub back in August when he and a female friend tangled with security guards. But the rapper struck a deal with prosecutors to pay the dirt cheap fee ... and in return they dropped the case.

Think about it -- $120 is less than 5 minimum bets at a $25 blackjack table ... less than buying a round of drinks for you and 5 friends ... and several hundred bucks less than bottle service in a club.

Now you know how to win money on the Strip.
