They made an honest mistake....these things happen. Haven't you made a mistake in the past?
They acknowledged the fact they made a mistake and have rectified the situation by sending you the correct ball. If you wanted the ball overnighted to you, thats fine, but you should have talked to them and said that you would pay the extra cost to overnight a 16 pound box. Otherwise, just be happy that they are making things right and enjoy the ball when it gets there. Besides that, you are getting the ball cheaper than you would at the Pro-Shop.
Is there any legitimate reason why you absolutely have to have the ball next day? Didn't think so. Buddies are a stand up group of guys that wouldn't try to screw someone over. The last time that I ordered a ball from them, they called me within a half hour to tell me that they didn't have the specs that I asked for and to ask if they could send me a ball that was close. They didn't have to do that, they could have just sent me whatever they had...but they didn't....great customer service and I will never have a problem ordering from them.
