Sellers may place items in their inventory on sale. Selecting any number greater than zero will place selected items on sale. For example, to put items on 10% off sale, type the number 10 in the sale field. Enter the number 0 in the sale field to remove the sale.
Selecting a negative number will increase prices of selected items by the percentage you specify. For example, enter the number -100 to double your prices. Numbers, both positive and negative, cannot be greater than 100.
