Expensive "U"s

Journeyman’s recent post about the New Living Translation reminded me of various discussions at church over new pew bibles recently. The new bibles will probably be Today’s New International Version. The American versions are printed in a font which is much easier to read than the English version and are about a third of the cost. The main (albeit minor) irritation is with differing spellings. In all the bibles we have looked at, the American version is much cheaper – which begs the question: are all the extra “u”s in words like neighbour and Saviour really much more expensive to print…?
