There's a new company called Pronto that has a product in beta that not only crawls your site, displays message toasts while visitors are looking at your products via a browser plug-in.
For instance, someone is looking at the widget your online store is selling and suddenly a window pops up telling your visitors that they can get this widget cheaper elsewhere and tries to direct your shoppers away from your store.
Basically, this takes something like a Shopping.com-type service one step further by incorporating it into the browser and the potential harm to all the smaller online stores is enormous.
Anyone running any kind of ecommerce or affiliate site will definitely want to block this:
