How much does it cost to purchase a proof copy? I plan to publish a book soon. About 105 pages, premium paperback, perfect bound. That option says its $6.05, and the 105 pages says $6.20 ($6.20 for 105 pages??). So is that just $12.25? What about shipping? I'm in Canada.
Also how come buying black and white on white gives me US letter option (21.59 x 27.94) but black and white on cream is US trade (15.24 x 22.86)?
