kanga thanks for your answer, but I thought about something that will send me an email or notification when there is a new auction without a need to search eBay everyday. Also It happens very often that the item is sold after it is listed, so I am not able to reach it.
I think that the feature that you are reffering to is now called Saved Searches. Thanks for pointing out. Well I checked it out, but unfortunately I got only one email even if plenty of items were added after that, so it is not a perfect solution.
In the meantime I looked through the Google Play store and found interesting app for Android - it is called Deals Tracker for eBay. It seems that It does excatly what I need. It notifies my as soon as there is a new item within my search without any delay.
