Product review (5 stars): Special Prime sale price of $5.99!!
The price WAS definitely RIGHT!!  We needed a new filter as the water was running SOOO slowly so I knew what was wrong.  Just by chance when I was looking for a replacement Amazon had it on a FABULOUS Prime buy for that day.  $5.99 -- normally these sell for around $40!! I couldn't believe the screen when I saw the price but that's what it cost.  Water is running lickety split again!!
