You are in sales, so you will understand this.
I ordered 500 hard cover books from the printer, they arrived today with the wrong isbn number and the price is listed as $19.95 instead of $24.95. What this means is that i will have no choice but sell it for $19.95 each. I lose $5 per book. Would this upset you? It has done a number on me, but, we are human and CRAP HAPPENS. We swallow our pride, put the ego aside and we move on.
