bartering is exchange of good(s)/service(s) for another good(s)/service(s).
The latest example I've witnessed: a church friend's family has goats. They give some of their excess milk (and milk products - cheese, etc.) to a neighbor has grows lots of vegetables, who in turns gives extra veggies to my friend's family.
One part of the exchange can be a good while the other part can be a service or both parts can be goods or services. So in my example, both parts are goods (milk for veggies), but both parts can be services (hair cut for babysitting) or one of each (hair cut for homemade jam).
So, out of curiosity, and a possible learning experience for all of us, what happened?
