Store is going downhill

3 months ago
The app indicated the item I needed was in stock at the Muncy store. I drive all the way to the Muncy store and lo and behold. They tell me it’s not in stock, “the app is never accurate”. The employees there are pretty much useless. But she did lead me to a display that had assorted pulleys but nothing like the one that Tractor Supply brags “it is original equipment.”
