If it's on the way, why not?! Saves a ton of money too since you will have a plan for meals and only be buying enough to make the meals you plan. I did that for a while when I worked right next door to my usual grocery stop. Had to stop when I moved to the boonies. And being nocturnal is normal for teenagers. It's just part of their psychology. I'd just let that be until a couple weeks before school starts then suggest they start going to bed at the time they would when school starts. If they don't take the suggestion, let them deal with being tired. If they're abusing the phone and tv priviledges, just take them away. Tell them they can earn them back when they start being appreciative. Privacy, eh, let em have it since they are out of your hair then. Make them do household chores or something to earn the right to have a phone and tv... I like the idea of buying food everyday as long as it's not out of your way.
