They started to change the way passports are produced. Now, they scan the photo, print it directly onto the inside front cover, and cover the whole information section with a holographic contact paper. I understand there's also a chip inside, somewhere.

$30.00 of the $97.00 is a fee that goes to the facility accepting the application. It's the same wherever you go.

But if your passport is within 15 years of its issue date, and it's still in reasonably good shape, you can renew it for the cost of photos and $67.00 to Uncle Sam, from the privacy of your own home. A little wear and tear around the edges, water spots from a little rain = reasonably good shape. Sent through the washer and the dryer, chewed by the dog = not good shape. (The last two examples are from life.)
