Addon for osCommerce Online Merchant v2.3.4.1 Edge

Its quite simple I have 2 requirements. 1) I have an add on for osCommerce that I have just updated to be BS compatible. However I want to add some more functionality to it. It basically allows you to update product prices all from one page and when you have entered all the updated prices simply press update. This much quicker that going into each product to update each price. At the moment if a product is on special offer that product in not available for update and has t be done manually. I want the ad don changed to show all products with normal price and special offer price. So Product xxx--------------Normal price----------%discount or value--------Special Price So you can simply update the normal price and then either input a % or actual discounted price. 2) I have a current add on which is started and need to be finished, display is ok and compatible but needs to completed to make submit button update database and for display to show changes. . It is a Group order update add-on. It simply lets you select a number of orders on the order page and update their status all at once rather than individually.
