Amazon is offering the second-generation Echo in red, in support of Product (RED) and its humanitarian efforts to combat HIV / AIDS. Similar to the arrangement it first offered last year, Amazon will donate $10 to the charity for each red Echo sold.

The specs are the same as any other second-generation Echo, except that it’s covered in red fabric. It costs $99.99 and is available for preorder now, although it officially launches on December 5th. It’s going to be discounted during Black Friday, though — down to $69, with $10 still going toward the charity — so that sounds like the better bargain.
