Adjust barter rates to suit your tastes. Do you want to make it more difficult to accumulate vast amounts of money from selling items? Do you want to decrease the effect that your Speech skill has on prices and lend some extra importance to the Speech perks? However, this is one of the features that can conflict with other mods, so if you don't want Trade & Barter to override the values set by another mod, simply make sure this feature is deselected. By default, it is already deselected.
Put a price tag on it. Successful bartering must result in the satisfaction of both parties. This can only happen if the items bartered are realistically valued. If you have an item you would like to trade, obtain an accurate appraisal. An item is only worth what someone is willing to pay for it. Therefore, do your research and look at the "selling" section on eBay to find out what online buyers have paid for similar items.
LOCATION - Prices are lower in smaller towns, but merchants also can't afford to pay you top septim for your goods. Cities are expensive, but there is more money to be made there. Merchants in cities charge higher prices when selling their wares, but they are also willing to pay more for premium goods in order to make sure that their shops stay well-stocked. The five major cities can now have their buying and selling rates set individually to reflect their size, wealth, access to supply and shipping routes, or status as a trading center.
Make the deal. After you've found a barter partner, get the agreement in writing. Make sure you detail what services or goods will be involved, the date of the exchange (or work to be done) and any recourse if either party reneges on their part of the deal. If you are working through a membership-based bartering association, they will likely provide all the structure and paperwork you need for the deal.
When two people each have items the other wants, both people can determine the values of the items and provide the amount that results in an optimal allocation of resources. Therefore, if an individual has 20 pounds of rice that he values at $10, he can exchange it with another individual who needs rice and who has something that the individual wants that's valued at $10. A person can also exchange an item for something that the individual does not need because there is a ready market to dispose of that item.
Other anthropologists have questioned whether barter is typically between "total" strangers, a form of barter known as "silent trade". Silent trade, also called silent barter, dumb barter ("dumb" here used in its old meaning of "mute"), or depot trade, is a method by which traders who cannot speak each other's language can trade without talking. However, Benjamin Orlove has shown that while barter occurs through "silent trade" (between strangers), it also occurs in commercial markets as well. "Because barter is a difficult way of conducting trade, it will occur only where there are strong institutional constraints on the use of money or where the barter symbolically denotes a special social relationship and is used in well-defined conditions. To sum up, multipurpose money in markets is like lubrication for machines - necessary for the most efficient function, but not necessary for the existence of the market itself."
