Almost as tenacious as Readers Digest and American Express. Harvard Business Review sent me another invitation to subscribe today. The accompanying letter offered a subscription for $89, but the coupon to mail back said it was $152. How can this be? The lower price is almost worth considering, but not quite. That's a six month price. I can and do subscribe to The Economist for $826 for three years of a weekly magazine. This week, the front cover again depicts the burning WTC. All prices quoted are in NZD.
