@Hawkeye thanks for the heads up. I'll give it a try.
I'm a convert to grocery delivery in my circumstances. I bike to work, and there aren't any grocery stores remotely on my way to work. The only ones even close to work are a Whole Foods, and an even more expensive specialty store.
The cheaper grocery stores are all the other direction from work, so getting there involves biking home, picking up the car, driving 15 minutes each way, and shopping at a place where the lines are chronically five or more people deep. Standing in line for ten minutes or more before reaching the register is the norm. Did I mention that the cheap grocery stores in my urban area are pretty dysfunctional?
I'll gladly tip somebody five bucks and pay a few bucks in a delivery fee to do a task that would have taken me an hour or more, and that's generally frustrating. Other people work cheap, and sometimes I'm happy to take them up on the offer.
Of course delivery would make way less sense if I drove past a Costco every day on my way home from work.
