Store subscribers get 1000+ listings for their $25 a month, as well as a slightly lower selling fee and a quarterly coupon for branded shipping supplies.
We also get promotional Free Listings. My Stores have for some months had over 10,000 available Free Listings, should I ever want them.
And we can organize our listings into our own categories, which I think of as the aisles in my Store.
I agree that visibility moves around.
My 'proof', such as it is, is based on the agreed fact that if we get sales, we get more visibility and thus more sales.
Recently another slowish Store has had a rush of sewing pattern sales, which have been in the doldrums since before Christmas.
And both in that Store and in this one, when I get a run of sales, they also tend to be in the same parts of the USA or even of the world.
Many years ago, I sold two stamps, two weeks apart, to two different cities in Liechtenstein. Never a sale there before, never one since. I believe the first sales led to visibility in Liechtenstein and another sale there.
Flimsy evidence, but memorable.
Normally about 80% of my sales on this account go to the USA, but this past month more than half have been to Canada (I am in Canada). Again, I believe that those Canadian sales from listings on dotCOM led to more visibility to Canadian buyers.
But as @yuzuha says. A sale is a sale. As long as I'm being seen where the people and the money are, I don't care how my listings rotate.
