When people meet to exchange one type of good for another, they both must want what the other is offering in exchange. Let's say that I have six chickens, and you have three sacks of flour. I really need and want your three sacks of flour, but you do not have a need for six chickens. You want two chickens, and a bushel of apples. This exchange would not be successful because we do not have an equal offering of our wants and needs.
There must be a dual coincidence of wants.
The double coincidence of wants is one of the major part of the Barter System.The two basic terms actually don't have any specific difference.
For example; the supplier of good A wants good B and the supplier of good B wants good A.

It can be used to compare the value of different products.
When you are saving money to buy something you want, you are trying to work really hard just to get that money to buy it with; however if you have the money but you decide not to buy that item, that it how you get over the coincidence of what you want.
Demerits of the barter system include the lack of common unit value and lack of system for storage of value or purchasing power. It is inefficient and has a lack of double coincidence of wants.
It was quite a coincidence!
