Don't be surprised if you see an Amazon-branded semi-trailer on the road this holiday season. The shopping giant just announced that it's snapped up "thousands" of trailers (the rear cargo portion of tractor-trailers) to beef up its shipping capabilities in North America, CNET reports. That'll be particularly useful as we approach the holidays, since it'll help to avoid delays and offer shoppers more time to select Amazon's speedy two-day and one-day shipping options. The company will still rely on partners for their drivers and trucks, and it's only using the trailers to move packages to its distribution centers. Amazon is already relying on couriers and branded vehicles for its same-day Prime Now service, as well as for AmazonFresh grocery deliveries, so there's a chance it could eventually compete with the likes of FedEx and UPS.
