Use Very High Price as Persuation Technique for Your Online Sales Page
Using a higher price will make the price you are asking seem much more reasonable. You need a tool to help you keep that in front of your visitor al the time.
Have a floating box (to the left, right, bottom or top of your page) showing your potential buyer a product that is much much (even ridiculously) higher price that what you are trying to sell. The floating box always stays visible even when the visitor scrolls up or down.
