BODY OF THE ADVERTISEMENT

The body is the "meat-and-potatoes" of the advertisement.  It must

• emphasize a central selling point;
• appeal to the needs of the target audience; and
• create a desire for the product.

Unlike a business sales letter, advertisements don't normally introduce the price unless the price is a central selling feature of the product (i.e. Spring Clearance Sale, 50% off, cheaper than the competition...).
