Hi @SoloTraveler and welcome. I’ll add some links that you may find helpful. Note that if you do a saved search on the website, then you will get a daily email of new listings based on your criteria. If the search is saved via the app, then you can set your phone notifications. I base my decision on how wide is my criteria, given I want to avoid my phone dinging too often
