When the email hit my Inbox announcing Net-a-Porter’s iPhone application I have to admit that I uttered a little groan. “Oh no”, cried my frugal inner voice (the one that tries to dissuade me from impulse purchases and other financial outlays that I will come to regret in the, not so distant, future), “do I really need to be able to buy $600 suede shoes or a $1,650 flannel dress when I’m sitting on the bus or waiting in line at the post office?”
