The e-commerce company already has six such grocery stores in the UK, and 32 in the United States.
There is also one Amazon Salon in central London, which allows customers to use immersive technology to try different hair styles and colours before getting a cut.
Amazon was already strongly placed in Britain before the pandemic, with growing dominance in the delivery sector.
During lockdown, it benefited hugely from the closure of non-essential bricks-and-mortar retail as well as from fundamental changes to consumer shopping habits.
The latest UK launch “will send a warning to the industry that competition could become even more fierce”, said analyst Richard Lim, of Retail Economics.
“Despite some of the challenges presented by supply chain disruptions and the impact of Brexit, Amazon has always played the long game,” he told AFP.
“A physical presence will provide loyal customers with a frictionless path to purchase, offering them the chance to touch, feel, experience and pick-up online orders in-store.”
