"List price" is the suggested retail price provided to us by our vendors. We make no representation that a substantial number of these products have been sold or offered for sale at the list price. Actual retail prices in your area may be substantially different. Since we sell products on a national basis, it is not possible to know if our merchandise is sold at list price in any particular location or at any particular time. "You Save" reflects the difference between our price and the vendor provided list price shown on our sites. Since the list price may be different than the actual retail prices in your area, you may not actually realize a savings of this amount.

Manufacturers sometimes ask that retailers not display a price if it drops below a certain amount. The "Click here to see Lowest Price" message indicates that the price of the item is so low that the manufacturer requested that it not be advertised (that is, displayed). In a brick-and-mortar store, you would probably have to ask a salesperson what the price of the product is. At eCOST, by clicking on "Click here to see Lowest Price" you are essentially asking to see the price, at which point we show it to you.
