Product review (5 stars): amazon to the rescue.
I had no choice on the specific filter for my refrigerator and tried obtaining it from the store where I bought the refrigerator.
they advised it was not in stock and would call me when it  was available. I decided to try Amazon for the first time in my life.
not only was it in stock at Amazon but it was in varied quantities (Cost Savings),  Free  Shipping (Cost Savings)  and  I had it  in
home in 2 days.  No gas wasted  to get it from the store.
The store called almost 2 weeks later  to advise they had  the  filters available.
