Here are two craigslist moves that can work in your favor:
a) Get two tickets to a concert, then close to the time of the show post an add looking for a woman to go with you, when you get some bites negotiate some head or more in exchange for a night out to see a band they love.
b) Many times chicks will post out of desperation. Car problems, rent is due, or they just want to fund a vacation or new dress. capitalize on that turn it into a mutual beneficial relationship.
