Why don't we show the price?
We wish we could. We set our prices independently, and because our price on this item is lower than the manufacturer allows us to show you, we need you to provide some information first. We realize that this is an inconvenience and we regularly provide this feedback to our manufacturers. We welcome your comments and suggestions on our forum.
