I got that e-mail as well BUT the real $200-300 discounts are for the iPad not the iPad 2. I had the 64GB in my shopping cart for $529 and I was SO excited - then I realized it was the old model, not the new one. I only want the iPad 2.
They also had iPad 2s for sale from the same link, but they weren't discounted. They have the 16GB and the 32GB for $629 and $729 - which is the regular price, AFAIK.
