I created a new category..... copied an item into that catagory that had attributes with different prices. Then edited the item's master category to the new one just copied into.

Then I created a new SaleMaker for 5% off on that category... pricerange 0 to 0.
Specials Condition: Ignore SaleCondition
Starts: Immediately
Expires: Never

When I look at the item the "Start at:" price is marked "Sale:$0.00" but the item is not discounted as the price is in the attributes.... shows the same price when I put it in my cart.

Issue is that the 5% should be subtracted from each attribute item to show the new price.
