While checking another site, I noticed Grocery Lists which caught my eye since as a concierge I happen to do food shopping for some of my clients. I find it more time consuming when I have to find my way around a new (to me at least) store. I am not aware of GPS software or Google Maps or Mapquest to show me the way around these unknown emporiums so you are not lost in the supermarket. Maybe it does exist. I do know for a fact (having worked in a supermarket many years ago) that we purchase items we did not intend to get as we negotiate various aisles. The store is set up to make us shop more. It is true also that we often write our lists aphazardly so reorganizing them in sections saves us time in the end. 'Grocery Lists' offers a collection of more than a 1000 shopping lists. Dig through it.
