When using the Edit Selected feature to update the attributes of selected products, any selected products using quantity pricing will not be updated if the price or sale-price attribute is modified. Instead, these products will be skipped, and you will see a message alerting you to products using quantity pricing that have not been updated. Please note that all attribute updates will be skipped for the products using quantity pricing, and not just the price and/or sale-price attributes.

All other selected products will be updated.
