We get this in the UK - I can order from Tesco or Asda and get it delivered to my door.
"Price promise" price matches lowest price in area for branded goods like Heinz baked beans. It's cheaper in UK to pick supermarket own brand, in which case there is the issue that I like Tesco baked beans but not Asda baked beans.
And Tesco offer a "as you would pick it yourself" on fresh food where they pick the longest shelf life fresh food. But Tesco failed and lost a lot of money in the US market.
I wonder why the UK has good supermarket delivery and the US does not.
