John Lewis is opening its first convenience store, to test a new method of delivering goods to shoppers.
The department store chain will open a small shop in London's St Pancras Station, where customers can also collect online orders as they commute.
Click and collect is already a popular option with the retailer's clientele, accounting for 33% of internet sales.
If the store proves successful, the company says it may launch similar branches at stations across the UK.
Tesco, Waitrose and parcel delivery firm InPost recently announced plans to provide click and collect services at London Tube stations, by installing secure collection points.
The BBC's business correspondent, Emma Simpson, says the ability to click and collect is the new frontier in the battle between retailers.
Asda has recently begun trialling temperature-controlled lockers where customers can pick up their shopping, and Tesco has delivery vans at a number of London tube stations where commuters can collect their orders.
"Click and collect" accounts for almost a fifth of all online sales for retailers with physical stores and websites - a figure that has quadrupled in just three years.
