With this short list of sites that we will show you today, you will facilitate this process, since it tracks the price of the product we want to buy among many online stores, thus offering the best magic to get what we need.
Youpil site:
The product you buy is placed in the search box and the site will search the four stores listed above in the introduction. It has an Android application, and the result appears in the form of columns with the prices found in each store. Unfortunately the link to Amazon is com. , The urge can not be customized by country, and the price is always in dollars. It is ideal for simple price comparison
Idealo:
Compare prices and also offers flights. The results show as you type in the search box what we want to buy, it has filters so that the correct result can be reached without losing a lot of time.
Kelkoo.es:
Compares up to 25 stores at the same time, with results grouped by categories. Sometimes it is possible to find discounts, although you will sometimes see the site things of type: "Galaxy Note 9 of 4000 euros for only 700", something that scares a bit.
twenga.es:
Compares more than 18 million products in more than 200 stores, being one of the most complete listings. Contains filters in the sidebar, including prices, although when searching for mobile phones, it always displays the security tools in the first place, making it difficult to access the first devices required.
Shopmania.es:
Much like the previous site, although it has a more complex but better appearance when it comes to displaying results.
