Calendars missing punched holes ...
Is anyone else suffering from missing punched holes in their calendar?
Somehow Lulu seem to be incapable of ensuring that a printer will punch a hole (and in the correct place too) as per the template - i.e. so that the calendar will hang on the wall open, with the month grid and photograph properly visible.
I have had this happen twice, but the attempts at resolution seem pretty feeble to me.
