Barter is the process of trading products, goods or services, for other products, goods or services. It is a simple method of transaction, frequently one in which no money is exchanged. Barter systems are often utilized between nations, and sometimes between a nation and a corporation. Barter also occurs between corporations or companies and other businesses, and sometimes between a business and an individual, or two individuals. In the United States, billions of dollars worth of goods and services are exchanged each year through bartering.
The troubles that the people of Venezuela are going through are horrible and in all reality, really shouldn’t be happening.  Venezuela has a tropical climate and is an oil producing country. They should at least be growing their own food in the countryside.  This would help those who are starving.  But those in power, the elite, don’t care about the common people and make it hard on them at every turn.  While the elites have access to the food, medicine and all the power they want from their electric grid, the common people have had to make due with what they can scrounge.
I wish I came up with this fantastic idea. SharedEarth is a free site that connects landowners with gardeners and farmers in need of space to grow crops (i.e. starting a home vegetable garden). You can find free access to land in exchange for sharing a little bit of produce with the landowner. In a time of a strong and growing local food movement and concerns about food safety, SharedEarth might just be the most important sharing site of all!

Still, Adam Smith really did seem to believe barter was real. He writes, “When the division of labour first began to take place, this power of exchanging must frequently have been very much clogged and embarrassed in its operations,” and then goes on to describe the inefficiencies of barter. And Beggs says that many textbooks sloppily seem to endorse this viewpoint. “They sort of use that fairy tale,” he explains.

Like in Venezuela, people are bartering for needs.  The important things that are sought right now seem to be food and medicine.  But at some point, people will be wanting a “taste” of their former life.  They will want something that reminds them of the life they had.  It could be as simple as a piece of chocolate or a nice new dress.  The important thing here will be timing, security, and perception.
Bartering is the exchange of goods or services. A barter exchange is an organization whose members contract with each other (or with the barter exchange) to exchange property or services. The term doesn't include arrangements that provide solely for the informal exchange of similar services on a noncommercial basis. Usually there's no exchange of cash. An example of bartering is a plumber exchanging plumbing services for the dental services of a dentist.
Some businesses that may not directly barter with customers may swap goods or services through membership-based trading exchanges such as ITEX or International Monetary Systems (IMS). By joining a trading network (which often charges fees), members can trade with other members for barter "dollars." Each transaction is subject to a minimal fee; the exchange facilitates the swap and manages the tax components of bartering such as issuing 1099-B forms to participating members. You may find a nearby exchange through the International Reciprocal Trade Association (IRTA) Membership Directory. Before you sign up and pay for a membership, however, make sure that members offer the types of goods and services you need. Otherwise, you may find yourself with barter money or credit that you cannot use.
Kids sure do grow out of their clothes rather quickly, and that’s where ThredUP comes in. They set up a cool shop for parents to swap clothing and toys with other parents whose kids are different ages. You can pick up a box full of clothes or toys for just $5 plus shipping, or post your own child’s used clothing for other users to pick from. Membership is free for everyone.
In trade, barter (derived from baretor[1]) is a system of exchange where participants in a transaction directly exchange goods or services for other goods or services without using a medium of exchange, such as money.[2] Economists distinguish barter from gift economies in many ways; barter, for example, features immediate reciprocal exchange, not delayed in time. Barter usually takes place on a bilateral basis, but may be multilateral (i.e., mediated through a trade exchange). In most developed countries, barter usually only exists parallel to monetary systems to a very limited extent. Market actors use barter as a replacement for money as the method of exchange in times of monetary crisis, such as when currency becomes unstable (e.g., hyperinflation or a deflationary spiral) or simply unavailable for conducting commerce. 

Especially prior to the Christmas holiday season, a gift and craft exchange can take the pinch out of your budget. Contact people within your network and arrange a day where people exchange homemade holiday decorations. You may not find everything you’re looking for, but you will likely find at least a few stocking stuffers – and the perfect price.
An online swap meet of sorts, at there is no bidding or money exchanged. Rather, you offer to trade the stuff you no longer want. You’ll then have the ability to choose from books, movies, CDs, and other items. The site doesn’t seem to have monthly charges, but you’ll be responsible for shipping costs associated with items you sell. Swap has its own free iPhone app for simple listing and searching.

The Internet has provided a medium for new growth in the bartering industry. This growth prompts the following reminder: Barter exchanges are required to file Form 1099-B.pdf, Proceeds From Broker and Barter Exchange Transactions, for all transactions unless an exception applies. Refer to Bartering in Publication 525, Taxable and Nontaxable Income, and the Form 1099-B Instructions, for additional information on this subject. Persons who don't contract with a barter exchange or who don't barter through a barter exchange but who trade services, aren't required to file Form 1099-B. However, they may be required to file Form 1099-MISC.pdf, Miscellaneous Income. Refer to the Form 1099-MISC Instructions to determine if you have to file this form. If you exchange property or services through a barter exchange, you should receive a Form 1099-B. The IRS also will receive the same information. 

When exchanging services, it’s important to remember that bartering is considered income. While you may be able to write off expenses you incur during the barter, you must claim the fair market value of the services you provided as income. For example, if you charge $60 an hour as a massage therapist, and you trade a one-hour massage for housecleaning services, you may have to claim the equivalent income. When you trade assets, you may even be responsible for tracking capital gains or losses. If you have any doubts or questions, consult the IRS website.
In Canada, barter continues to thrive. The largest b2b barter exchange is Tradebank, founded in 1987. P2P bartering has seen a renaissance in major Canadian cities through Bunz - built as a network of Facebook groups that went on to become a stand-alone bartering based app in January 2016. Within the first year, Bunz accumulated over 75,000 users[29] in over 200 cities worldwide.
Adam Smith, the father of modern economics, sought to demonstrate that markets (and economies) pre-existed the state, and hence should be free of government regulation[citation needed]. He argued (against conventional wisdom) that money was not the creation of governments. Markets emerged, in his view, out of the division of labour, by which individuals began to specialize in specific crafts and hence had to depend on others for subsistence goods. These goods were first exchanged by barter. Specialization depended on trade, but was hindered by the "double coincidence of wants" which barter requires, i.e., for the exchange to occur, each participant must want what the other has. To complete this hypothetical history, craftsmen would stockpile one particular good, be it salt or metal, that they thought no one would refuse. This is the origin of money according to Smith. Money, as a universally desired medium of exchange, allows each half of the transaction to be separated.[3]
But the thing is, EVERY economy has collapsed at one point or another.  People who believe that it can’t happen in the United States of America are not critically thinking.  It is a possibility!   The economic fundamentals of the 2008 crash haven’t changed.  In fact, the Powers that Be printed even more money.  We are in even more debt!  Many say we have an economic system that is not sustainable.
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]
So as you consider items to stockpile, you should think about items that are necessary, but might not take up a lot of space.  Referring back to Mark Goodwin’s book mentioned above, one thing the main characters looked for were canning lids and rings.  They don’t take up a lot of space and in a real collapse situation, they will be really worth it!
Other countries, though, do not have the reporting requirement that the U.S. does concerning proceeds from barter transactions, but taxation is handled the same way as a cash transaction. If one barters for a profit, one pays the appropriate tax; if one generates a loss in the transaction, they have a loss. Bartering for business is also taxed accordingly as business income or business expense. Many barter exchanges require that one register as a business.
With 70,000 members posting items they would like to barter with or for, there is a good possibility you can find what you are looking for at U-Exchange. Listings are available from all over the world, and the search feature lets you narrow down your choices by keywords. There is no charge for membership or listings, as advertisers pay to sponsor the site.
Modern barter and trade has evolved considerably to become an effective method of increasing sales, conserving cash, moving inventory, and making use of excess production capacity for businesses around the world. Businesses in a barter earn trade credits (instead of cash) that are deposited into their account. They then have the ability to purchase goods and services from other members utilizing their trade credits – they are not obligated to purchase from those whom they sold to, and vice versa. The exchange plays an important role because they provide the record-keeping, brokering expertise and monthly statements to each member. Commercial exchanges make money by charging a commission on each transaction either all on the buy side, all on the sell side, or a combination of both. Transaction fees typically run between 8 and 15%.
For instance, each time Apple releases a new version of the iPhone, the second-hand market for older versions of the iPhone enjoys a flurry of activity. However, you do have to be as careful with the barter of used goods as you would be with the purchase of used goods. Be sure everything is in working order and shows no signs of significant damage. 

Bartering for goods and services is a centuries-old art. Recently, the idea of trading with your neighbors and within your community has received a big boost and taken on a modern spin. Combining our often-materialistic, ownership-based society with the Internet’s ability to bring buyers, sellers, and traders together, online bartering has sparked a wealth of new sites and communities.
