Hi
It shows 12 ( or 16 ) at a time but it does not use the same ones. It depends on what auction you're looking at.
You can feature a listing and it will be in the store window!
But go to another listing that has a ending time that is a lot different and see if it has different listings in it's store window.
It is supposed to every so many hours rotate listings. I believe that is how the code works.
Thanks
