It's not the online ordering that I need to save time on, it's having to make a trip NOW because I forgot to order more ahead of time. That extra trip to Target takes a whole heck of a lot longer than 10 seconds, and when I consider how many extra Target runs I make every year it adds up fast.
This only applies if you're incapable of buying the stuff ahead of time without the button. I suppose some people might qualify for that, but is it really a common thing? Don't you have your phone right there already?
Last month I had to go to store at least twice in the morning before work because we ran out of milk and my two year old was close to having mental breakdown without cereals for breakfast. We use combination of Google Shopping Express, Walmart and Safeway delivery services - they are godsend and save us enormous amount of time. Unfortunately Amazon Fresh is not available where we live.
Having one second ordering for regular staples will marketdly improve ordering process, especially if buttons are reliable and convinient to use.
