Don't worry, there are a few reasons that the message bar doesn't show up. The PriceBlink add-on is designed to be discreet, and therefore only shows up when there is relevant information to the product you are shopping for.
The PriceBlink message bar will not show up if there are not retailer coupons or product price comparison available. Even though the PriceBlink add-on provides information from thousands of retailers, we do not have universal retailer coverage, so it is possible that you are on a site that the PriceBlink add-on does not currently work with.
In certain cases, it is possible that the PriceBlink add-on was not able to determine what the product you are looking at is. We are working hard to improve the system all the time, so if you come across a problem, please feel free to contact us.
If you have any concerns that the PriceBlink add-on is not working, please check out this test link. If your add-on is working properly, you should see the yellow bar appear at the top of your page.
