I cannot see why Amazon would want to acquire a high street supermarket.

I can. They have one store chain in America and need physical presence to learn the bits they don't know, about UK shoppers. I did notice Amazon lockers in a Morrisons I go to. (because they have a noticeboard I can use for Stroud Ceilidhs publicity). Oats are cheaper there too. And Painsbury's don't always have notice boards. And curiously Painsbury's have mixed policies on being collection points for E-Bay. My nearest Argos & Painsbury's don't. Go figure. Such inconsistency only alienates customers.

I did once complain to Lidl about a remaindered product missing an item and they offered alternative stores (for obsolete stuff!) to swap out the product but I suggested they paid for the bit at about 1 GBP and after sticking to my guns they gave me 5 GBP. go figure.

Asda and Morrisons wanted a store in Stroud, Aldi did also. Aldi won, and the site is being cleared, not that far from Painsbury's
