The world’s biggest bricks and mortar retailer has been working on its own paid membership model over the past 18 months, which is expected to be called Walmart+.

According to Vox, Walmart is planning to start testing the service as early as March.

The retail titan is said to be looking at a number of options and perks that are not yet offered by Amazon, including giving customers the ability to order goods via text message.

That service was previously offered by Jet Black, the premium personal shopping business incubated through Walmart’s Store No.8 programme, before it was shut down earlier this month.
