It seems like you do. If you click on the light blue "kit" button next to the item name in the area where you select quantity and such, it specifies that you get 2 X-Narrow Baskets, 2 Narrow Baskets, 2 X-Narrow Gliders, and 2 Narrow Gliders.
Hope this was more useful than the answer from the Container Store saying "Please contact our customer solutions department for further assistance with your purchase." If we have to contact the store, what is the point in the Q&A section???
