In a move which has a lot in common with that exhibited by retailer Best Buy last month, Amazon.com is now offering customers who bought a HD-DVD player before they were discontinued store credit of $50. Anyone who bought a player before the 23rd of February qualifies and the $50 credit offer will be honored until this time next year (April 9th 2009). Certainly good news for anyone who invested in the now defunct format, while being a good move for Amazon as the offer is likely to stimulate more spending (which is what they want to happen after all).
