Amazon 透過各種技術整合的比較好 (像是先前發表無人機空運的技術 Amazon Prime Air)，而 Wal-Mart 則是跟 Uber/Lyft 這樣的公司配合：「Wal-Mart Plans to Test Grocery Delivery Through Uber, Lyft」。
不過可以看到運費不算低，如果買的東西不多的話：
The move steps up competition with Amazon’s burgeoning grocery-delivery service and provides a potential new avenue of growth for Uber and Lyft. The idea is to let Wal-Mart customers pick out groceries online and then have employees fill the order and give it to one of the ride-hailing companies’ drivers. Shoppers will pay a $7-to-$10 delivery charge to Wal-Mart to have the groceries brought to their door.
