I have a 762 page book, letter, to print. 740 pages is doable for $13. 741 pages is doable only with hardcopy and so for...>$30. yikes. I had hoped that a few new paper choices would appear after 10 years. nothing in between?
You can do a 740 page book perfect bound. But the price I got after using a couple of coupon codes is about $17.
It's also very easy to reduce a 760 page book to 740. Condense the font in your manuscript by .1. It's hardly noticible.
My Grammaire du philippin, made public this week, has 724 pages. It used to have over 740 pages. I slightly reduced the four margins, and removed a couple of secondary developments.
