Product review (5 stars): Thanks again to Amazon!
Our Maytag dryer belt broke on a Sunday.  The local big box store assured me that they had the part.  I drug the broken belt out of the machine and started disassembling the machine while my wife drove all the way across town to retrieve the part.  I disassemble the dryer and waited....and waited....and waited.  She finally returned, after she and the store employee looked in every bin at the store.  Then came the bad news.....they really didn't have it.  My wife commented that the employee indicated that a belt might not be available for this machine.

I then clicked on my trusty Amazon link and very quickly found the part (<a data-hook="product-link-linked" class="a-link-normal" href="/Maytag-Drum-Belt-Part-no-312959/dp/B004PILT0I/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Maytag Drum Belt - Part no. 312959</a>), which was identified by good graphics AND the part number.  The belt arrived in 2 days and, as advertised, and fit the machine perfectly.

All of the above was achieved for less than $9, which is light years better than the price of a new dryer.  Needless to say, I'm a big fan of Amazon Prime!
