US-based retailer Walmart is expanding its grocery delivery service to markets in Orlando, Florida; and Dallas, Texas.

Last year, it used transport company Uber Technologies to implement its delivery service on a pilot basis.

The service aims to provide an easier selection for consumers while buying groceries.

Walmart e-commerce operations vice-president Mike Turner said: “We’re working hard to find a way to get you fresh, quality groceries, all the while keeping a little more time on your calendar.”

"The current move is an extension of the company’s strategy of exploring different delivery options in key markets across the US."

Consumers can place an order online or through a mobile browser, as well as select a time to conveniently receive their products.

Once the order is placed, Walmart workers pick up the requested items and scan them to ensure an accurate and complete order.

The workers will then request an Uber to come to the store, collect the order and deliver it to the customer.

The current move is an extension of the company’s strategy of exploring different delivery options in key markets across the US.

Walmart is delivering general merchandise deliveries in certain areas through its associates while testing grocery delivery using Walmart trucks and drivers in other markets.

The announcement comes at a time when major retailers are expanding delivery services.

Discount retailer Target recently decided to expand its new next-day essentials delivery service to two additional markets in the US, whereas German-based supermarket chain Aldi announced its plans to launch same-day delivery service in three US cities by the end of the month.
