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. 

Economists since the times of Adam Smith (1723-1790), looking at non-specific pre-modern societies as examples, have used the inefficiency of barter to explain the emergence of money, of "the" economy, and hence of the discipline of economics itself.[3] However, ethnographic studies have shown that no present or past society has used barter without any other medium of exchange or measurement, nor have anthropologists found evidence that money emerged from barter, instead finding that gift-giving (credit extended on a personal basis with an inter-personal balance maintained over the long term) was the most usual means of exchange of goods and services.[4]
She was about to quit the project when she received a cascade of good news: six new women signed up as Barter Babes, more than she’d ever had before at one time. Then City Television contacted her for an interview segment—one of her Barter Babes had mentioned her trade to a friend at the station. After that, social media mentions of Barter Babes blew up.

Consumer-based barter systems aren’t the only trade in town, either. In the GTA, there is a robust business-to-business barter system, similar to wir but on a smaller scale. Businesses sign up for a service—there are several available—and trade unbilled work hours or dust-covered inventory for goods and services they couldn’t otherwise afford, especially during recessionary times: often things that attract top talent and retain big clients, such as advertising, promotional gear or client perks.
