Asda is teaming up with Just Eat to offer customers the chance to order groceries to their door in just 30 minutes, the supermarket said.
The grocer will also expand a previous trial with the food delivery service to allow hungry shoppers to order freshly cooked pizzas from Asda stores.
Chief executive Roger Burnley explained: “Our partnership with Just Eat that launched last year to deliver pizza direct to customers was a huge success, so much so that we’re rolling it out to up to 50 stores by the end of the year.
“This project demonstrated how partnering with complimentary brands can enhance our offer to customers, as a result I am delighted to confirm that we’re extending our work with Just Eat to trial an express grocery delivery service from two stores.
“This will focus on delivering product to customers from around 100 essential lines within 30 minutes.”
The groceries trial will launch at two stores – Fosse Park in Leicester, and Asda’s Sutton store. A wholesale retail operation to appeal to independent retailers will also be rolled out at Asda’s Patchway store in Bristol.
His comments come as supermarkets are testing new ways to get shoppers to spend money with them.
For years they have cashed in on the rise and rise of convenience stores and customers buying food to cook and eat the same day.
But with Asda not having any convenience stores, bosses will be hoping the trial can eat into rivals Tesco and Sainsbury’s large portfolio of smaller sites.
However, Mr Burnley said there were no plans to launch into the convenience market with smaller stores.
Aldi and Lidl have both announced in recent months that they will open or expand onto high streets.
Lidl recently said it would open a store in central London, and Aldi is in the process of converting a handful of sites into “Aldi Local” stores – although they will be around twice the size of a typical Tesco Extra or Sainsbury’s Local.
But Mr Burnley said there were no plans for Asda to move into smaller stores. He said: “In terms of convenience stores, we have no plans. At this point there is plenty of convenience space in the market.”
Just Eat has been trying to innovate its offer, after losing market share to rivals Deliveroo and Uber Eats, by hiring its own riders to make deliveries.
On Wednesday it also announced a link-up with Greggs to deliver sausage rolls and other pastries across London, Newcastle and Glasgow.
