From the 'everything is getting more expensive' files:

The .org top level domain (TLD)is soon to become more expensive for those that want a domain. The Public Interest Registry (PIR) which manages the .org TLD has informed ICANN that they're hiking fees later this year.
The wholesale price for a .org domain will rise to $6.75 effective November 9, 2008. Currently PIR charges $6.15 for a .org domain name registration (0.15 cents of whcih goes directly to ICANN as a transaction fee).

The increase in .org pricing will come a month after .com and .net pricing (managed by VeriSign) get hiked. The wholesale price of a .com domain on October 1, 2008 will go from $6.42 to $6.86 while .net will rise from $3.85 to $4.23.
