Following similar moves by Best Buy and Wal-Mart, Amazon.com is also trying to make up for HD DVDís failure by offering a $50 store credit to those who purchased an HD DVD player from it before February 23.

The offer is good through April 9, 2009 so you have a full year to use the credit. Sure, it's not as good as getting your cash back, but unlike Wal-Martís offer which requires buyers return their HD DVD hardware and have the original receipt, with Amazon at least you get to keep your HD DVD player and use it as a DVD upscaler. This is surely a smart way to build goodwill with your customers when a technology becomes obsolete.
