Ahah, nice troll. But I still prefer to both those options the way I do it : I just shop on store's website and ask for delivery. This allows me to have shopping lists that I can use as templates, I can shop any hour of the day and take time to compare products.
Granted, this is especially a good fit for me because I work from home and can receive deliveries any time.
It's interesting that you see just about every permutation of shopping and delivery options out there.
You have online shopping and delivery as you mention. I'd do this more myself if there were a service I liked where I live.
One of the local chains around here started up a "To Go" service recently. You shop online and pick up. I assume the market here is people who can easily drive but may not be very mobile or have young kids that just make it a hassle to do the picking themselves. (My anecdotal observation is this service isn't being used much.)
And this case is pretty much what a lot of markets in cities have been doing forever. (Often smaller markets but I believe Whole Foods does this in some locations as well.)
