Product review (2 stars): Price shifting in 1 weeks time is really annoying
I had been buying  a different brand filter but thought that the price was a little bit high so I went shopping around on Amazon for a different brand that might work and be a little cheaper.  The previous brand had been selling for almost $25.  I bought this one for a little over $17.  I only bought one because I wanted to make sure that it worked right.  It came, it fit, it seems to work fine in my Whirlpool side by side.  So I went back to order more and the price had gone up over $3 in less than a week.  I went ahead and ordered 1 more, but the price shifting thing really ticks me off.  Makes me feel like the price hike is done on purpose when I buy it.
