To $135 July 13th. Here's an article from USA today.
The renewal form online says $75. The cost of a new passport is $100 ($75 plus a $25 admin fee).
I can't believe they want $82 just to add addl pages to a passport. Last year when I renewed my passport, I specifically asked for the expanded booklet (52 pages) but the usual screw ups resulted in me getting a normal passport. Now I have to hope that my passport doesn't get stamped too often.
When did they raise the renewal price to $100? I renewed mine in November 2008 for $75.
