Product review (5 stars): Great price for replacement!
Well I had my new refrigerator for less than a year.  The original part (rail, center crisper) broke so I bought a replacement part through Whirlpool's parts distributor.  The replacement part from Whirlpool lasted two weeks and then broke.  Not that we have heavy things in our crisper.  Anyway I thought I'd look at Amazon.  I saved money and the part arrived quickly.  It has lasted so far and I am very pleased.
