suburban Paris shopping with car?

I'm renting a car and moving my daughter from Bxl to central Paris next week for university there. As I'll have a car there for a few days, I'd like to stock her up with food and supplies. We'd like to hit an area in suburban Paris or nearby town that has a Carrefour and hopefully a Lidl/Aldi right nearby, to load up the car with supplies for her for the term. Can anyone think of a good place to drive to?? (she's in 6th Arrond., so someplace S or W of central Paris best?; I don't mind traveling out on a motorway a bit, we just want to take advantage of having the car for a few days by doing one big shop. Also, any outlet shopping centres around Paris?
