I don't know about you, but most of my product searches start with Google. And most of my online purchases end with me doing some last minute searching for coupon codes.
Billeo Offer Assistant is a Firefox extension that serves up deals and discounts right in your Bing, Google, and Yahoo search results. It's not perfect, but it can definitely save you time--and help you find deals you might otherwise have missed.
After installing the plug-in and restarting Firefox, just search for a product as you normally would. Then look for the Billeo icon next to any of your results. If you see one, mouse over it to see what deals are available.
In this example, I looked for "Planet Earth Blu-ray" and found offers from both American Express and Discovery.com (though only the latter was applicable unless I was planning to spend more than $75).
Billeo pulls these offers from more than 1,500 retailers, from Best Buy to Target. I particularly like how I can see Bing Cashback offers within Google searches. But all too often, the items I searched for had few or no discounts available. "Modern Warfare 2"? Nothing. Zune HD? Zilch. Palm Pre Plus? Big minus. Offer Assistant would be a lot more compelling if it provided more actual offers.
Still, I appreciate the convenience, and think anyone serious about saving money would do well to at least check it out.
