The Special Offers Page

To have products appear on your Special Offers page, you need to set up a discount on one or more of your products. Whilst editing a product, take a look at the Price Details panel, and you will see a Discount Type dropdown menu. Use that to set whatever discount you want, Save it, and the product will then automatically appear on your Special Offers page.

Next, if you take a look at the Settings > Design Settings section of the control panel and click on the Image Graphics link, the page will scroll down to a panel that allows you to set whether or not you would like use Special Offer Images (small graphics that appear on top of your product images if a special offer is applied).
