I need a new water filter for refrigerator I bought this summer. Are filters stocked in store, or do I have to order?

I concur with Tristan Perry sometimes you have to order online because of the variety of different refrigerators you just need to go ahead and check at the information desk.

Depends, some filters are available but range to about 60-90$ i would personally order it offline. Online its around 20-30$ depending on the fridge and filter type.
