For the most part I find the app useful. I even like the update that uses a popup window when I tap on products without losing my search. But low stars Because I can't ADD to my favorite list!! If I see something in the app I like but can't buy yet, I have to add it to my cart, then go to the website that's Not an app to go back and add it to my fav list. STUPID!! And yes, totally worth losing so many stars. Fix it, and you'll get them back. Also annoyed with a popup that blocks scanner use.
