Costs play an important role in setting international prices. Travelers abroad are often surprised to find that goods that are relatively inexpensive at home may carry outrageously higher price tags in order countries. A pair of Levi's selling for $30 in the United States might cost $5.29 in Norway, and an Oral-B toothbrush selling for $2.49 at home may cost $10 in china. Conversely, a Gucci handbag going for only $140 in Milan, Italy, might fetch $240 in the United States. In some cases, such price escalation may result from differences in selling strategies or market conditions. In most instances, however, it is simply a result of the higher costs of selling in another country-the additional costs of operations, product modifications, shipping and insurance, import tariffs and taxes, exchange-rate fluctuations, and physical distribution.
