NVC will raise up the IV Bill on January 1, 2008 to $400.00
Important: If the NVC generates (ex. IV Bill) on the
weekend. (ex. Sat, Dec 15)
Then, the NVC will mail it and post mark it on a
weekday which will be Monday and the NVC automated system will say (ex. Mon, Dec 17)
Please Note: Please check dates very carefully because of the weekends and have your generated dates correct!
Thank you!

Thanks for the link. Looks like those who get the payment mailed out before the first can save $20. From the USCIS Fees page.
