awaii. The basic idea ofinternational trade and investment is simple: each country produces goods or services that can beeither consumed at home or exported to other countries.The main difference between domestic trade and international trade is the use of foreigncurrencies to pay for the goods and services crossing international borders. Although global tradeis often added up in U.S. dollars, the trading itself involves various currencies. Japanesevideocassette recorder is paid for in German marks in Berlin, and German cars are paid for inU.S. dollars in Boston. Indian tea, Brazilian coffee, and American films are sold around theworld in currencies as diverse as Turkish liras and Mexican pesos.Whenever a country imports or exports goods and services, there is a resulting flow of funds:money returns to the exporting nation, and money flows out of the importing nation. Trade andinvestment is a two-way street that, with a minimum of trade barriers, usually makes everyonebetter off.In a interlinked global economy, consumers are given the opportunity to buy the best products atthe best prices. By opening up markets, a government allows its citizens to produce and exportthose things they are best at and to import the rest, choosing from whatever the world has tooffer.Some trade barriers will always exist as long as any two countries have different sets of laws.However, when a country decides to protect its economy by erecting artificial trade barriers, theresult is often damaging to everyone, including those people whose barriers were meant toprotect.The Great Depression of the 1930s, for example, spread around the world when the United Statesdecided to erect trade barriers to protect local producers. As other countries retaliated, trade

of empty food packets are read in the bin and put on the shopping list which is forwarded to the nearest supermarket.A few hours later, a courier arrives with the food, and it nobody is at home, the products are left in the "Skybox"- a largescale post box with special compartments for food products that need to be kept cool or frozen. The family receives a text on the mobile phone or an e-mail informing them that the shopping has been delivered."Lots of things are mush simpler in this house than in my old home," says Ursi," and I got used to it all really quickly, without reading instruction booklets.\\ And because of the Skybox, I don`t need to rush home to pick up the shopping."For her 12-eyear-old daughter Grace, the home is "simply cool", especially the television, which is watched cinema-style with Dolby sound via a projector in the ceiling that puts the images on the walls. The device can also play videos and can bring the newspaper into the living room over the Internet.Security is another advantage. The front door, for example, is opened by a fingerprint system, and the entire house can be monitored, even from a distance, by mobile phone.Ursi adds^ "" All the devices in the house, such as the washing machine in the celar, let me know when they are finished if I want them to, whether I`m in the kitchen or upstairs in the office. I get the devices, computer."The Futurelife house is owned and operated by Otto Beisheim Holding, in co-operation with and another 60 partner firms that supply the devices, computers and software.Despite all the ultra-modern appliances, Ursi admits she misses one thing about her old home- the open fire.

Sales contract
The sales contract is the legally binding agreement reached by the seller and
the buyer (the parties to the contract). It can be made orally or in writing, although
it is usual for the contract to be drawn up in writing to prevent disputes.
There are three ways to conclude a sales contract:
1. This is the most normal way of concluding a sales contract, because most
offers are non-binding. As non-binding offers can be changed or withdrawn at any
time, a sales contract does not exist until the seller confirms the order, making any
changes impossible.
2. Sellers tend to make firm offers when trading in goods where the prices
fluctuate a lot. They set a fixed and if the buyer doesn't place an order within the
period of time where, this price is valid, the offer with expires. The seller can then
make another offer with new prices to keep up with the prices on the market.
3. In this case, if the buyer is not interested in the goods, he is expected to
return them within a certain period of time, otherwise he will have to pay for them.
After a sales contract has been concluded, the seller and buyer have to fulfil
certain liabilities (that means there are certain things they have to do).
The seller's liabilities are:
- To deliver the goods on time and in perfect condition.
- To ensure that the title to the goods is transferred to the buyer — in other words, the
seller has to make sure that the buyer becomes the owner of the goods. This is
normally done by passing a special document, the document of title, to the buyer.
The buyer’s liabilities are:
- To accept delivery of the goods (this prevents him changing his mind after the
goods have been sent).
- To pay for the goods within the time agreed.
If one party doesn't fulfill its liabilities, the contract is broken (this is called
breach of contract). In this case the other party (injured party) can claim
compensation.
