When you buy either the 3G or DX, you can get a $25 Amazon Gift Card along with it. What a great start for Mom’s new Kindle e-book collection. If you go to the product page for either item, Amazon includes details on how to include the $25 Gift Card.
There doesn’t appear to be an actual offer end date, but Amazon said that the promotion will run while supplies last. So, the sooner the better, and before Mother’s Day of course.
