"Amazon.com Special Offer: $50 Off a Future Purchase
Dear Amazon.com Customer,
As someone who purchased an HD DVD player from us before February 23, 2008,* you might like to hear about a special offer available from Amazon.com.
New technologies don't always work out as planned. We at Amazon.com value our customer relationships more than anything and would like to support customers who purchased these players by offering a credit good for $50 off any products sold by Amazon.com.** Just use promotional code XXXXXXXXXX when checking out. The code is valid through April 9, 2009, so you have plenty of time to use your credit. Purchases from third-party merchants on our site are not eligible.
**Offer cannot be used to pay for special-order titles, e-books or downloadable e-content, wireless service plans, gift certificates, gift-wrap, taxes, or shipping and handling charges. $50.00 promotional credit is per HD DVD player purchased prior to February 23, 2008--up to 10 units for a maximum credit of $500.00."
