Then it circles back to these people being idiots . It especially grinds my gear that most of these Herbalife pushers look fat and are trying to sell dreams to other fat people . <| sep |> Shilling ? I ' m not shilling dude . Promise ya . I love ThinkPads , I also love MacBooks , I also do third party Apple MacBook repairs . <| sep |> Yep . You use it on the barcode and get either search engine results or an item comparison depending on the appI use Amazon for most of my comparisons in most cases . A few examples of where it ' s really benefited me Was at Toys R Us a few weeks back to make a preorder for the PlayStation VR . I scan it and get a search engine result detailing a promotion that was going on at Gamestops near me that sold the same package but with refurbished cameras and controllers but for about $ 50 bucks cheaper . Best of all is it was in stock . Saved a few hundred on a TV when I scanned it on Sears compared to Amazon . Same with dishwasher and dryer . I almost always save some money by going to big retailers and using it as a price matching negotiation . It ' s a win win because Retailers either price match or I buy elsewhere .
