No, no, no. You have NO idea of Friday in store availability. Those that chose in store are taking a chance. They may or may not get one. It's always this way. Those who chose to pay a few bucks for Friday delivery will almost certain get it then. It's a choice. It's far from robbery. Will you be the first to yell and scream if you go to the store on Friday and they don't have one for you?
That's a good point. It assumes that those who paid extra for shipping will get them on Friday, though! Let's hope that assumption comes true.
