Apply To Products: Specifies which type of products will be affected by this price adjustment. "All Products" will affect every product in the affected categories. "Products on Sale" will affect only products where the sale price is less than the original price. "Products not on Sale" will affect only products where the sale price is equal to the original price.

Apply To Price: Specifies whether the price adjustment will be made to the products' sale price, original price, or both. When applying the adjustment to only the "Sale Price", you will have the option for the price adjustment of the sale price to be based from the current sale price or the current original price.

Price Adjustment: Configure the adjustment settings that will be made to your price changes. You can increase or decrease a price by a specified percentage or fixed dollar amount. If your "Apply To Price" is set to "Sale Price", you can configure the price adjustment to be based on the current "Sale Price" (default) or you can configure the price adjustment to be based on the current "Original Price". Example: If I were to apply a 10% off sale on my categories and wanted the new sale prices to be 10% off of the products' "current original price" instead of 10% off the price's current "Sale Price", I would select the price adjustment to be Decrease By Percentage 10% on current original price. If I later wanted to remove the 10% off sale, I can restore the sale prices back to their current original price by doing an Increase By Amount $0 on current original price. This tool will restrict you from a price going below zero dollars, from the sale price being greater than the original price, and from the original price being less than the sale price.
