grocery shopping

Okay, now I'm having one of those "what next?!" feelings.... I was babysitting tonight for a family I regularly sit for, and when they got home we were talking and somehow got onto the subject of grocery shopping. It seems that Harris Teeter has a service now where people can shop online and just pick up their groceries at a scheduled time (or later) for a fee.... The mom I was talking to has been using this service so regularly that she has avoided taking her baby and toddler to the grocery store for the past 7 or 8 months! I'm trying to get my mind around this -- what would life have been like if I had not taken my kids to the grocery store, and indeed not had to do any grocery shopping in person, for all those 25 years I had kids at home? It's something to think about....
