Never has stock

I am an avid user of Apple and having an apple store in Westville is convenient, BUT it would be convenient if there was stock. I have been there on several occassions either for screen cleaner of iphone 6 covers and they have always been out of stock and the staff are never too helpful in regards to solutions or other recommendations. in that store, the staff need to be vibey and enjoy working there but they always look bored to death. PLEASE apple sort this out.
