10. In most states in America, a sales tax (8 to 10%) is added to the price of every item purchased. In the state of Illinois, the sales tax is anywhere from 7.25% to 8%. Take a look at the receipt provided below. The sales tax is underlined on the receipt. A receipt is a small sheet of paper that spells out the details of a monetary transaction (e.g., the price of each individual item, purchased with or without a coupon, the sales tax imposed, and the total amount paid by the buyer). It is a good idea to keep all receipts in a safe place, so that if you'd like to return an item, you can do so. Most Department stores in America allow shoppers to return items (except for food items) within a period of 30 days after the date of purchase. During this time, you have the option of either exchanging an item for another similar or similarly priced item or returning it altogether and getting your money back. States in which no sales tax is imposed on purchases include New York and Oregon. Such states are therefore said to be good for major shopping (i.e., large scale shopping).
