The only way I would shop for groceries on line like that is if I was a shut-in and physically unable to get to a grocery store myself or had absolutely no one else who could get them for me. I know people have busy lives but seriously... this is not something I see that needs to be "automated". I like to eyball and examine the food I'm buying myself. I check nutritional value, expiration/sell by dates, etc. And how does it work when it comes to meat, produce, and other perishables? I'd never want someone else to do my choosing for me if I could help it 'cause what they chose for me may not be what I'd choose.
