If the user selects one store, this store will show on the top, which allow the user to navigate at the later time. Border shows all the product types on the top panel. It dose not have the feature stores featuring as Amazon. When the user selects a store, Amazon shows categories of products for this store on the top of the left-hand panel. It also shows the featured categories in the center of the page.
Border provides the same feature but the categories are on the bottom of the left-hand panel.
The user has to scroll down to find the categories. Some users may not aware there are categories that they can use. In Amazon, the color of the text of the selected store is changed, which tells the users where they are. But Border does not have this feature. The users have to look at the content of the page to find out which page they are currently in.
