Right, sorry I keep forgetting to post about this. Basically what's going on is that the printing company has been taking a really long time getting back to my emails, and things are moving along really slowly. Plus the initial quote they gave me was much higher than last time, so I spent some time trying to get them to lower the price.
But now things are finally moving forward, I'll be getting the proofs next week, and hopefully the books will be printed and ready by the end of this month.
