     Going shopping seems easy but actually it takes a lot of learning especially in America. In fact many
Americans who are not so well-off often shop at "sales" or at special stores that sell things at low prices
which you may find interesting. In America the important rule of dressing is that one should change his
or her clothes every day. For example in an American college neither professors nor students are seen in
the same clothes two days in a row. So you may find it necessary to buy more clothes than you have in
China. While you are shopping in the States you will discover that prices range considerably from time to
time. The purchase of used second-hand clothing furniture or other household articles may be an excellent
way of saving money. Most second-hand clothes are of pretty good quality. If you are going to settle down
in the States and want some furniture you may go to a"loan closet" where furniture rents at low cost or
you may also go to a"furniture exchange" place in the community.
     Sheets blankets and other bedclothes go on sale in most communities twice a year. Advertisements for
"white sales" on bed linen towels etc. often appear in January as well as in May June or July. Once or
twice every season there will be"garage sales" where you can get almost anything from a yacht to a pair
of shoes at low prices. Prices at"discount stores" and "thrift shops" are also as low as you can imagine.
     When shopping for food you should look for special prices for various items that are put on sale weekly.
To economize it would be a good idea for you to plan the weekly menu according to what is on sale
including in it the meats vegetables fruits etc. that can be bought at special prices that week.
     Exchange and return policies vary from store to store. You should also keep in mind that exchange and
return policies for sales items can be different from standard store policies especially if the price of the items
has been reduced. Ask the merchant about their exchange and return policies before making your purchase.
Obtaining an exchange or a return without a store receipt is often difficult. So to save yourself the headache
you'd better hold on to any paper or other proof of purchase.
