There are many things from the brick & mortar marketing world which can be transferred to the online world.
One of them is creating a visual contrast between ‘prices’ in your content. What I mean is, you can write out say a special offer in a particular way that makes the ‘deal’ price look much better than the regular price by virtue of the contrast, visually.
Let’s say, the normal ‘price’ on an item is normally $10 and you are offering it at $7 for a week. Why not present the two as $10.00 vs. $7?
I created a Video Offer on another page so you can go see it as an example of this concept in use.
