Amazon has a great deal on Whirlpool 4396841P PUR Push Button Side-by-Side
Refrigerator Water Filter, 2-Pack. The price is $35.59 after 20% discount.
The discount is automatically applied during checkout.

The 20% discount applies to other filters as well but the price is not as
low as this one.
With my luck I bought these exact filters a week ago for $45.
