Put a price tag on it. Successful bartering must result in the satisfaction of both parties. This can only happen if the items bartered are realistically valued. If you have an item you would like to trade, obtain an accurate appraisal. An item is only worth what someone is willing to pay for it. Therefore, do your research and look at the "selling" section on eBay to find out what online buyers have paid for similar items.
Inevitably some people may feel like they were taken advantage of. One way to diminish inequities is to engage in dollar-for-dollar trades. For example, if you would like to trade your housecleaning service for someone’s couch, try to break down the goods and services to the dollar amount. If the two of you decide that the value of the couch is worth $200, why don’t you supply a gift certificate for $200 worth of housecleaning services? It’s a wise course and ensures all parties know what they are getting and what they are offering.
This sort of scenario was so undesirable that societies must have created money to facilitate trade, argues Smith. Aristotle had similar ideas, and they’re by now a fixture in just about every introductory economics textbook. “In simple, early economies, people engaged in barter,” reads one. (“The American Indian with a pony to dispose of had to wait until he met another Indian who wanted a pony and at the same time was able and willing to give for it a blanket or other commodity that he himself desired,” read an earlier one.)
