Buy Now Hover Button

You don't have to pay for JavaScript code, there is always a free version around somewhere

One script that seems to be a popular item for internet marketers to try to sell to other internet marketers is one that will create a hovering "Buy Now" box that stays visible on the screen while the person reads their compelling content that convinces them that they need to buy whatever is being sold. When they decide to buy the button to do so is right there. Well my script here doesn't have quite as many bells and whistles as that script but you can easily modify this script to do everything that theirs can do and more without having to buy anything.
