I work with a number of home-based bakers and home food processors and recently ran across two interesting Food Delivery Businesses that I think are working well; although time will tell. Both companies are located in North Carolina and one is in the Chapel Hill area while the other is across town in the Raleigh area. The both deliver organic and natural products direct from small farms and local food processors in their communities. You purchase small boxes or containers of food that in most instances is picked or produced just hours before delivery. I love this idea, particularly since I work from home and I am often times too busy to shop or even visit my local Farmers' Market.
Check them out for yourself.

This will not work for all areas and in all cities but with more folks working from home like myself, putting in 10-12 hour days, this is a blessing.
