You can run special promotions on any product listed in your catalog, as long as you never go below the product's MAP price.
Setting a product up for a special promotion is fairly simple.
Navigate to Catalog > Manage Products and select the product you wish to list as a special promotion.
Once inside the product, select Prices from the list of options on the left-hand side.
- Special Price - Defines the sale price of the item.
- Special Price Dates - Defines how long the product will be listed under Special Promotions and how long the Special Price will be valid.
- Once the "To" date has been reached, the product will be removed from the Special Promotions section and will return to being listed for the normal price.
Save the product.
Once you are done adding products to be listed as Special Promotions, you can continue to:
System > Cache Management.
System > Index Management.
