Base price list: is the price list from which a current or new price list inherits price values.

SKU pricing: is a simple pricing method that uses the product or SKU catalog page to assign a list price and, optionally, a sale price, to the SKU. SKU prices are independent of price lists, but you can use the two pricing methods together if the pricing model for your sites permits it. See Creating and Managing SKUs for information about setting SKU pricing..

Volume pricing: Sets the price of a product based on the number of items purchased. Price lists support two popular volume pricing models: bulk pricing and tiered pricing. Bulk pricing calculates the price of a product based on the minimum quantity ordered. Tiered pricing calculates the price of a product using fixed quantity or weight at different pricing levels. See Defining Volume Pricing for more information.
