Otsledit is a universal price tracker with its help you can track the prices of products in any online store and amazon is no exception. To track an item on amazon, open the item you are interested in and use the "track price" button to start tracking the price of the product. In the Watchlist you will have a track of the tracked product, see the example on the gif below.
Otsledit will notify you when the price has changed. In the watchlist you can see the history of changes. You can also set up email notifications.
If the tracker did not find the price of the product yourself, you can select it manually via the "create track" button, see the guide below.
Thus, you can conclude that Otsledit is an excellent Amazon price tracker, but it can track not only the price, but for example the number of reviews, description, etc.
