Why not prepay groceries?
sidsavara: I had the same issue which I think is, you don't want to waste time standing in line shopping.  I found this (shopping for food) was a huge waste of time in my cooking workflow, so I hired someone to cook for me (won't spam it here, it was on hacker news before when I blogged about it - much to my happiness and genuine surprise)One thing I have been wondering about is a grocery delivery service, and make it very specific - Costco groceries only, on a certain day a week, and perhaps say no especially bulky items (case by case basis). It seems to me if I could get maybe 5-10 people interested, it would be worth someone's while with a truck (and a couple friends) to go do our shopping while they are shopping anyway.In my mind, shopping takes time as follows:  Driving + Physically walking around store to get items + waiting in line + Payment + load car + Drive homeIf one person did all the shopping for multiple people and had a close by rendezvous point (for the clients to pay/pick up their food), both driving times and time waiting remain constant.  Walking around the store will increase slightly, as would payment and load time (since more items must be rung up and loaded)It seems to me though that this increase in time required may be on the order of 10-15 minutes per client.  If I am willing to pay 5-10 bucks for this service, you could make an easy 20-100 bucks an hour, or probably ~50ish on average.
