Prices can vary depending on the market being served. Because Dell sells its computers directly to consumers all around the world, the Dell Web site makes it easy to compare prices for various markets. Go to www.dell.com. Begin on the Dell Canada site and determine the price of a Dimension 3000 desktop computer. Next go to the Dell United Kingdom website and another more country of your choice to find the price of the same computer. (If you need to convert currency, go to www.xe.com.) How does the price of the desktop computer vary? What would account for these differences in price?
