Product price comparisons at your fingertips

Shopping Assistant is an extension for the Opera browser that helps you make informed online purchases.

When you’re shopping for something online, there’s nothing more frustrating than realizing you could’ve bought the same product for cheaper elsewhere on the web. Shopping Assistant aims to fix that potential problem for you.

Shopping Assistant is a simple extension that will help you compare prices. When you search for a product on a retailer’s site, Shopping Assistant will automatically show you similar products from other popular shopping websites to help you compare.

Shopping Assistant supports price comparisons on eBay, Best Buy, Walmart, Newegg, Buy.com, and Amazon. It also offers price histories for each product sold on Amazon, which is a nice added perk.

If you’re big on browsing privacy though, note that Shopping Assistant collects usage data via Google Analytics. It also only supports merchant websites in Canada, China, Germany, France, Italy, the United Kingdom, and the United States.

Shopping Assistant is a great way to compare product prices online before buying.
