If you can figure out what they’re for, you can have them:
HPCKJ7-N2Y9-CMWVKW-EVFV-B8H2E4
FWCX29-8YKK-JXHHE9-8CH9-E82TZ4
PCP88R-7YK6-4YGHT6-KGET-EE4EPE
MCH7CB-EEMF-XRWCX4-PG4R-4PWP84
Update 09/14/2010: Here’s another code, and if you’re wondering what it’s for, the date is a big hint.
VB9W8-4MMC6-XPMVD-DW2T6-3MKV3
