Have you checked out the Pounce feature on etsy? Pounce is found on the home page next to the treasury option.
There are two options, you can look at shops that haven't had a sale yet on etsy or you can see what the latest sales are.
I rely on pounce to tell me what is selling on etsy.
Not only does it list what sold but it also shows some of the other items in that shop. It is a great tool for getting sales. I know I have made may purchases from there.
If I sell something I have more of like supplies or epatterns, I relist right away so that someone using Pounce will find that item still in my shop.
