This new service is available on the web, and for iOS and Android users, and lets you save your favorite products and shop when the price drops. If you found a product that you’d like to buy but you’re waiting for a better price, you can save it to Yellowbag and organize it in the category you think it belongs. The guys at YellowBag boast with the fact that they track prices of 93% online products worldwide, and that is mostly true. I tried a couple of links and almost all of them worked. Sometimes their system doesn’t get the price right, but you can set it manually and the choose which is the price that you are looking for. And when that product gets discounted to your desired price, you will receive a notification. You can set as much as 20 price alerts, and to get more, you need to invite your friends to use the platform, as well. Thus, for every friend who joins Yellowbag, you’ll get 10 pricealerts extra. You can invite them by mail or by using a specialized link for that. The app is very well-designed, comes with a clean user interface and doesn’t have any advertisements at all. Yellowbag is a company operating from the Netherlands, founded in 2014 by online entrepreneurs Paul Aelen and Jasper van Elferen.
