Founders Andrew Kurland and Joe Marrapodi created their e-commerce negotiation site, Greentoe, out of frustration. The two were spending too much time trying to find the best deals online. That was proving time-consuming and difficult…

The site works like this: You want to buy, say, a new Canon EOS Rebel camera and you want the best price you can get. But you don’t want to spend a lot of time looking. Greentoe recruits a bunch of vetted online retailers. It then simplifies the process by showing you the average price and the lowest price for each product currently available online. You are then able to say how much you are personally willing to pay for that product.

Going with our EOS Rebel theme here, you see that the price for the kind of camera you want is around $549-$594 online. We found it on Amazon for $749 (and that was with a $50 savings offer). You decide you would like to buy this camera for the much lower price of $460. The Greentoe meter will let you know whether you’ve got a good chance or not to get that price. You are lucky on this one. The seller agrees to the price. Congrats, you’ve made a deal!
