The Specials module is a great tool to use on your osCommerce site for selling your dropship products.  The difference between a product marked as Specials and a product marked as Featured is that the Specials will be displayed on your site, often on the main page, with the old price and your new price.  The products will be displayed in the "Specials" info-box section on your store.

Somel osCommerce installs might notl have the Specials Module, but this contribution can easily be installed. 

It is very easy to set products as Special.

1- Log into your osCommerce CRE Loaded store's main Admin menu
2- Go to the menu for Categories/Products
3- Select the link under Categories/Products called "Specials"  (Navigating the admin menu is very easy.  For example, you control products marked as Specials through the main link called "Specials".  You just need to learn which main Menu's are used for which functions.  For example, the Categories/Products menu controls most of the main functions for modules that use the product data and apply it to different modules on your pages.
4- From the Specials link you will be taken to the Specials main menu.  There will be no product data here if this is the first time you have added a product as a Special. 
5- From the Specials menu, select the "new product" button.
6- Use the "Product:" drop down menu to select the product that you want to mark as a special.
7- Use the "Special Price:" to set the new price for your special
8-      Use the "Expiry Date:" if you want the special for that product to end at a certain date.

Specials Notes:
