Condition, Pretext, Objection: more than sales terminology

In sales, we are confronted with objections, pretexts, and conditions day in and day out. “Sales 101,” I hear you say. True. But my point is: Do you really know how to distinguish these three? Even more importantly, are you able to identify them in a negotiation? And do you know how to react in each case? I believe that this is where many sales professionals can up their game.
