mid-15c., apparently from Old French barater "to barter, cheat, deceive, haggle" (also, "to have sexual intercourse"), 12c., of uncertain origin, perhaps from a Celtic language (cf. Irish brath "treachery"). Connection between "trading" and "cheating" exists in several languages. Related: Bartered; bartering. The noun is first recorded 1590s, from the verb.
STOLEN GOODS - Don't expect any favors from Fences. Selling stolen items is going to cost you, so don't expect to get top dollar for ill-gotten goods. Tonila is exempt (actually all Thieves Guild & Dark Brotherhood fences are exempt, but in the vanilla game this just applies to Tonila). Any mod-added merchants who have been made members of the Thieves Guild or Dark Brotherhood faction will also be exempt. Options: -25% to -5% worse prices.
Bartering does have its limitations. Many bigger (i.e., chain) businesses will not entertain the idea and even smaller organizations may limit the amount of goods or services for which they will barter (i.e., they may not agree to a 100% barter arrangement and instead require that you make at least partial payment). But in an economic crunch, bartering can be a great way to get the goods and services you need without having to pull money out of your pocket.
While the original idea for Rehash was to design clothing out of recycled clothes, it eventually evolved into a site for trading clothes with other users. Members can trade their unwanted stuff (clothing and accessories) with others who are looking for new items for their wardrobe, and vice-versa. Rehash also acts as a social community where users can get green living advice, read articles, request items, and attend swap events. Membership is free to interested parties.
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.
When you load the menu option, the values you see displayed will be the values currently in use by your game. Vanilla values are 3.3 and 2.0. If the menu is displaying different values, then you have a mod installed which is already adjusting these two settings. If you choose to select a new setting, Trade & Barter will override the settings from the other mod. If at any time you wish to revert the settings back to those made by another mod, simply deselect this setting and reload your game. You will need to reload your game before the changes from Trade & Barter are fully canceled out.
MERCHANT GOLD - Trade & Barter gives you the option to set higher base gold amounts for each of the different vendor types.If you have another mod that alters the "VendorGold" leveled lists then you will have to decide if you wish to load Trade & Barter before or after the other mod. In most cases, I would recommend loading Trade & Barter after the other mod to take advantage of the flexibility and options provided by Trade & Barter. However, some mods, such as Economics of Skyrim, should be loaded AFTER Trade & Barter, so that this mod does not overwrite their changes.  

INDEPENDENT ADJUSTMENT - One issue with adjusting the barter values is that these settings change both the Buy and Sell prices. This can make it difficult to find a nice balance if you're trying to lower your selling prices without making the buying prices ridiculously high. Personally, I really like the challenge created by being forced to sell my gear at greatly reduced rates, but I dislike the extreme inflation that occurs when I then want to buy something. Therefore, the Independent Adjustments will allow you to increase or decrease the buying & selling prices independently of one another. This is something I've not seen in any other mod, and in my opinion, it's one of the best, and most useful, features included in this mod.
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.
SOME SUGGESTIONS - With all these different variables, you may be wondering what the best settings are to achieve a good balance in your game. Of course this will depend on what you want. Many people (myself included) like to make trade more difficult. I also like to set the barter settings relatively close to de-emphasize Speech skill and place more importance on the Speech perks.

Bartering services is best reserved for when you were going to make a purchase anyway. So instead of bartering your dog grooming services for an emergency plumber, you could establish an agreement with your shampoo supplier. You know you're going to need shampoo to run your business. So offer to perform a pet pedicure in exchange for an equal value of shampoo each month.
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.

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!
