Asda is launching a one-hour home delivery service for busy households.
But the speedy service comes at a price, as each delivery slot will set you back £8.50.
At the moment, only customers living within a three-mile radius of its stores in Halifax, Rotherham and Poole can use the service.
If it proves successful, then the supermarket could expand it to other parts of the UK.
Shoppers can order up to 70 items and have them delivered within an hour, or they can purchase an unlimited basket which can be delivered within a four-hour window.
Asda isn't the only supermarket to launch a one-hour service, but it claims it is the first grocer to offer its full online product range alongside the speedy delivery.
Tesco has recently expanded its own Whoosh one-hour delivery service to 11 more stores, following a successful trial at one branch in Wolverhampton.
The supermarket charges £5 for the speedy service and there is an additional £2 charge if you spend under £15.
Sainsbury's operates its Chop Chop one-hour delivery, which it expanded to 50 stores in 20 cities last year, which also has a delivery cost of £4.99.
Waitrose has announced plans to shut down its own Rapid delivery service, which it launched in 2018, saying it would instead focus on expanding its partnership with Deliveroo.
And finally, Morrisons offers same-day rapid deliveries as part of its tie-up with Amazon, which also offers customers its own Amazon Fresh products.
Morrisons, Tesco and Sainsbury's also have delivery services through Deliveroo, Uber Eats, Amazon and other providers - although none offer a full range of products.
Asda is also extending its partnership with Uber Eats from 200 to more than 300 stores, with more than 500 products available.
This includes fruit, vegetables, beer, wine and spirits and meals for rapid delivery.
Supermarkets have seen a huge increase in online orders during the coronavirus crisis, with all the major grocers adding thousands of delivery slots to cope with the demand.
Simon Gregg, Asda's vice president of online grocery, said: "After successfully trialling an Express Delivery service, we know this is something that our customers want as part of our online grocery proposition and we are delighted to be able to offer this service to even more customers.
"The launch of our new Express Delivery service and extension of our existing partnership with Uber Eats to 300 stores means that customers can get their order delivered to the doorstep at market-leading pace."
