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!
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.

There is no charge for membership or listings, as advertisers pay to sponsor the site.
You must include in gross income in the year of receipt the fair market value of goods or services received from bartering. Generally, you report this income on Form 1040, Schedule C.pdf, Profit or Loss from Business (Sole Proprietorship), or Form 1040, Schedule C-EZ.pdf, Net Profit from Business (Sole Proprietorship). If you failed to report this income, correct your return by filing a Form 1040X.pdf, Amended U.S. Individual Income Tax Return. Refer to Topic No. 308 and Should I File an Amended Return? for information on filing an amended return.

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.

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.
It’s hard to answer that without actually seeing a modern gift economy in action. Luckily, modern gift economies actually do exist. On a small scale, they exist among friends, who might lend each other a vacuum or a cup of flour. There’s even an example of a gift economy on a much larger scale, albeit one that’s not always in operation: The Rainbow Gathering, an annual festival in which about 10,000 people gather for a month in the woods (it rotates among various national forests around the country each year) and agree not to bring any money. Groups of attendees set up “kitchens,” in which they prepare and serve food for thousands of people every day, all for free. Classical economists might guess that people would take advantage of such a system, but, sure enough, everyone is fed, and the people who don’t cook play music, set up trails, teach classes, gather firewood, and perform in plays, among other things.

Men from the visiting group sit quietly while women of the opposite moiety come over and give them cloth, hit them, and invite them to copulate. They take any liberty they choose with the men, amid amusement and applause, while the singing and dancing continue. Women try to undo the men’s loin coverings or touch their penises, and to drag them from the “ring place” for coitus. The men go with their … partners, with a show of reluctance to copulate in the bushes away from the fires which light up the dancers. They may give the women tobacco or beads. When the women return, they give part of this tobacco to their own husbands.
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]
Bartering is the trading of one product or service for another. Usually there is no exchange of cash. Barter may take place on an informal one-on-one basis between individuals and businesses, or it can take place on a third party basis through a barter exchange company. A barter exchange is any person or organization with members or clients that contract with each other (or with the barter exchange) to jointly trade or barter property or services. The term does not include arrangements that provide solely for the informal exchange of similar services on a noncommercial basis.
Are you self-employed and tired of only having your pets to talk to at home? Visiting a new city and need to find a space to hold a meeting with potential clients? If so, LiquidSpace can help. Using their iPhone or iPad app, members scan through available work or meeting space, book the space for specific times, and get directions and access to other services that the space provides. The company is debuting in the San Francisco Bay Area soon, and they hope to expand nationwide quickly.
Companies may want to barter their products for other products because they do not have the credit or cash to buy those goods. It is an efficient way to trade because the risks of foreign exchange are eliminated. The most common contemporary example of business-to-business barter transactions is an exchange of advertising time or space; it is typical for smaller firms to trade the rights to advertise on each others' business spaces. Bartering also occurs among companies and individuals. For example, an accounting firm can provide an accounting report for an electrician in exchange for having its offices rewired by the electrician.
To try a time bank, search online for one in your local area using How time banks are managed varies according to the region, so it is important (and often mandatory) to attend an initial meeting that explains the general rules of your local chapter. Once you do this, you’re ready to start trading away. Your services and contacts are identified through the local time bank website.
Can you teach a skill like canning or cooking from scratch?  Food staples will be more readily available than the processed food many are used to buying at the grocery store and fast food.  And although many in the preparedness community know how to can and cook from scratch, your common everyday American doesn’t.  They wouldn’t know what to do with flour, eggs, and a little oil.

Unlike one-on-one bartering, members of exchanges are not obligated to barter or purchase directly from a seller. Instead, when a barter exchange member sells a product or a service to another member, their barter account is credited for the fair market value of the sale. When a barter exchange member buys, the account is debited for the fair market value of the purchase.

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.

When barter has appeared, it wasn’t as part of a purely barter economy, and money didn’t emerge from it—rather, it emerged from money. After Rome fell, for instance, Europeans used barter as a substitute for the Roman currency people had gotten used to. “In most of the cases we know about, [barter] takes place between people who are familiar with the use of money, but for one reason or another, don’t have a lot of it around,” explains David Graeber, an anthropology professor at the London School of Economics.
