You may desire to show that the price of a product is under the suggested retail price or is being discounted. A great way to do this is noted below in the title and description fields.
Create your text in a word processing program, such as Microsoft Word, that supports font colors and strike-through of text. Use the copy/paste feature to place it in the description field as noted below.
You may click the "HTML" button to see how the text is formatted for color and strike-through in the description field.
Add the discount information into the title field and the description field as noted in the example below.
Or stack the strike-through may work better if your are using the grid store template.
