Westfield Labs is trialling a same-day delivery pilot in two of its US shopping centres over the Christmas period.

Shoppers at its Century City centre in Los Angeles and Valley Fair in Santa Clara will have the same-day delivery option through a partnership with Deliv.

Deliv is also trialling the scheme with mall operators Simon Property Group and Macerich.

Shoppers request the delivery and leave their purchased items at the store. Retailers book the delivery at the point of sale.

Options include items delivered to their home or another chosen local destination for a rate of $5. If shoppers have valet parked, they can have their bags delivered to their car for free too.

All items are delivered using fully insured crowdsourcing delivery drivers within two hours. Deliveries are within 12 miles of the centre.

“There is a huge opportunity to empower the retail ecosystem through converging new digital technologies into physical environments that make products and services available to shoppers, anytime and anywhere at our shopping centers,” said Kevin McKenzie, global chief digital Officer of Westfield. “Our Westfield Labs team is focused on piloting emerging technologies and services, like Deliv, that will help enhance and personalize the overall retailer and shopper experience.”

The trial will run until January 5.
