The wife has been talking about starting up a company that does just this. Not just groceries but fast food, hardware store... Whatever. Kind of a call in butler. Seems that it is taking hold again.
The online grocery market has certainly gone through its share of ups and downs. However, over the past few years there have been a bunch of stories about a next generation of online grocery stores that seem to be getting more traction. One of the more famous is FreshDirect in New York City -- where online grocery shopping makes a lot more sense. Apparently, residents there agree, as a new study shows that more than half of NYC residents have tried online groceries -- though, that doesn't mean they all have been happy with it. Still, it does suggest that there's demand for such a service in some places (especially urban), if it's done right.
