For a subscription fee of $29 per month you can have a more professional look and more exposure. We give you a store template that includes the ability to add a cover photo and tag line. It also has price, category and keyword filters.
On our header bar, one can also search by Stores, which will only search on those seller with Store Upgrades.
The bottom line is that you're telling a potential customer that you are a professional seller and that they should have confidence in buying from you.
Over time, we will be adding additional bells and whistles to the Stores as well, that other Sellers will not have exposure to.
