Wal-Mart has considered implementing a system in which store customers deliver packages to online consumers.
According to NBC News, the world's biggest retailer would provide shopping discounts for those willing to deliver goods to online purchasers who live en route to customers' homes.
"This is at the brain-storming stage, but it's possible in a year or two," said Jeff McAllister, senior vice president of Walmart U.S. innovations.
Joel Anderson, Walmart.com's U.S. chief executive, said in an interview with Reuters that this could potentially be "crowdsourced."
However, this potential customer delivery system might present a number of legal issues. Perhaps the leading concern would be the notion of a total stranger transporting packages rather than an insured driver from a professional delivery company.
Wal-Mart currently uses carriers like FedEx Corp for delivery from stores - or, in the case of a same-day delivery service called Walmart To Go that is being tested in five metro areas, its own delivery trucks.
