barter.

"I'll give you this if you give me that..." Simply put.

Don't tell me you have nothing to barter because I know you do!
Everyone has something to offer whether it be something you no longer use or a service/skill you can offer.
The easiest way to barter is to de-clutter your house. Go through everything-- particularly electronics, books, gently used clothes and get-to tossing (make a pile marked 'barter').
One website I've found that works well is www.craigslist.org. It's a non-profit site that lets you check out things that people are looking to get rid of as well as post what you no longer need.
You may not make much money from this but at least your house will be clutter free (or have less of it) AND pick up something you need!
Artists, musicians, teachers... you can barter your skills.
These are just a couple examples but put on your thinking caps... I'm sure you will come up with something!
