When we bought our new two-story building at the beginning of 2006 we thought it would last us for 10 years. Well, we have already had to build an extension for our retail division which is now complete (thank goodness - no more sawing and hammering, dust, polyurethane smells etc!).
This now holds more books than you'll find in any Paper Plus store. Although NZ sales have fallen in the last year or so, foreign sales are significantly up - the "information super-highway" of the 1990s is finally starting to be one.
