Checkout emperor.....I'm totally using that.
Also on the bag issue. My wife started carrying in her own bags a few years ago. I will say it's so much nicer using your own bag versus the plastic bags. The environment impact is obvious but it's overall just a nicer set up. We can get pretty much all our weekly groceries in 3-4 bags. It makes it way better to load/unload at the car and at the house. Takes a bit to get accustomed to but once you do you'll never go back to plastic bags.
