May 12, 2008 the post office will increase their postage rates again! This not only includes first-class stamps to 42 cents, but other mail too (Priority, Express, Media Mail, special package services, etc.). Exactly how much on the other items will be announced later.
Here is a LINK to the current information on the postal website.
This does mean I will have to increase my shipping prices to cover all the new charges. But I will not increase until the new rates take effect. You have to remember it is not only the mailing rate to you that increases, but all the items shipped to me for the project increases (printed books, packaging material, office supplies for the project, etc.). So we have to cover all these added cost to keep the project going.
I won't change the base book price, unless the printer changes their cost per book.
