打折就是在原来售价的基础上降价销售，几折则表示实际售价占原来售价的成数。注意：10%就是一成，也就是一折，所以八折，就意味着实际售价是原来售价的80%。
A discount is a sale at a reduced price based on the original selling price. The discount indicates the percentage of the actual selling price to the original selling price. Note: 10% of the original selling price, which is 90% off; so 20% off means that the actual selling price is 80% of the original selling price.
