You must add the item to the cart and go through checkout to see the discount. It will come up as $39.99 at first, but there will be a $30 discount applied.
Shipping is around $5 and tax varies by state, so the $16 is an estimate but should be pretty close.
Also, Sony has free shipping on orders over $25, so if you're looking for other things, stack them up to get out of the shipping cost.
There's a good description on Amazon with a comparison chart and reviews. Reviews are very mixed, depending on your need, so it may be helpful to read some of those before jumping on this deal.
