What happens if we make a deal and thirty to sixty days after delivery the price goes down and you didn't get the best possible price ? How do I handle that ?   Well , these things happens , I know that . You just have to stay straight with me .   Right ! So how do I do that ? What will make you happy ?   Well , I suggest you just keep me posted.That should do it.That way the burden is on me to decide when to buy , not you .   Excuse me ?   Yeah , it really is that simple.Every time there's a change in the items we do business on , you let me know . That's all you need to do .   What kind of change , just in prices ?
