Thanks Mike. We had wanted to offer 25% off the most expensive products, but we are going to offer sitewide.
The answer is still the same. Set the price lower in your admin. Manage Products Each product has a "List Price" AND a Price which allows you sell a "Product" at a discount or a sale. If you enter both a "List Price" and a "Price", when the package shows for selection, it shows the list price $9.95 and the price $5.95. Of course you will have to do the math if you want to do a percentage discount to enter the currency amount. If that's not what you mean, then please clarify your question more.
