Dude, you're almost next door to The Five Wits (in PA). I live all the way in Georgia and without express shipping the wig still came in like a week. So if you order it now, you should have no worries. But FYI express was only like an extra. $3.
Also, I've never had a problem with their wigs concealing my hair. Just buy a light colored wig cap to go under it. Which is something you should be doing anyway. If still unsure, email them.
