Borders is doing some work to their website, and if you go their now you are given the message:
We're Sorry!
Our site will be back soon.
We're implementing site improvements and invite you to check back after 8:00 AM.
To make it up to you, use promo code THANKS712 and get 30% off the list price of any one item at Borders.com.
In the small type it says all electronics, including ereaders, are excluded.
It also says certain ebooks are excluded, see the product page to find which ones. I suspect this would be agency books.
