There's a difference between the app and the store
The app shows what's in stock and how much. I will say when we went last weekend they were out of stock of A LOT of the furniture particularly shelves.
If you find something you like, the page where you found it should give you the option to receive an email or a text (I think), that will notify you when the item is back in stock. If it's a popular item be prepared to grab it before it disappears. You can buy it and pick it up from the store.
The store is your best source. They can look the item up on spot and provide direct information.
Call them before. They can check for you
If you have a stock number or if you have a picture of the item you can actually use the special lens if you are a Samsung user
What about calling the store?
