I dunno about sales but might be worth going in anyway. Last year I went in on boxing day cos I got a few gift cards for presents, mad as hell in there, people everywhere. In the mad rush at the checkouts I noticed my bill was about $70 lower than I had thought, when I got to the car and checked my docket some of the stuff had not been rung up (all that haste in trying to move people on?). Xmas bargain for me anyway, I'm sure I'll get a few gifts cards again and I'm sure I'll pop in on boxing day!
