I work for a company that is automating UPS, FedEx and Amazon facilities, so I've asked this myself. The estimated number of packages shipped by Amazon makes up between 30-40% of the total shipments by the big 3 (UPS, FedEx and USPS). They do in fact get a hell of a discount for volume shipping, but that's only part of the story. What causes a package to take 3 or more days by the big three is method of transport (ground/air), distance from source to target, and cost/benefit. Here's the breakdown. Say you live in Cleveland and you want to send a package to Phoenix. If you send it UPS, it will go from the local dropoff to their hub in Louisville, KY, probably by ground. From there it will likely be sent via air to their hub in Ontario, CA (southern California, not Canada). Then it will be sent from there to the distribution center in Phoenix (likely by air), and then out for delivery. This whole process will take about 5 days. What makes Amazon able to trim time off of this is that their warehouses and distribution centers are located in the same cites as the hubs. For example, one of the main FedEx hubs is in Memphis, TN and the Amazon warehouse is a 10-minute drive from there. So the trip to get it on an airplane is almost negligable. Lastly there's a cost/benefit situation that might delay a package. So using my example above, let's say instead of sending the package to Phoenix, you're sending it to a remote location like Midland, TX. In this case the pakage would probably go from Louisville to Dallas and then trucked out west, that truck servicing perhaps a dozen west Texas cities. Unless that truck is 60%+ full, it will sit in the bay until it gets enough packages. Basically it's not worth it for the truck to leave empty. Here's where it's worth it to Amazon to offer the 2-day shipping. By creating a system that makes people in remote areas able to cheaply order items that they can't get locally, the trucks to remote areas are more likely to be full. The tl;dr version: when you order a pakage through amazon, it can be on a plane within a couple of hours, arrive at a nearby city that day, and be in your town the following day out for delivery; and because of their volume with the shipping companies their costs are minimal.

r/amazonprime on Reddit: So how DOES Amazon Prime Shipping work?
March 5, 2025 -

Thought we might collect up some insights into how AMZN does this…

We all know that Amazon Prime is supposed to come with ‘one to two day shipping speed, after it ships’. Seems pretty clear….. takes a bit for them to find the item, they put it in a box and ship it a while later- takes one or two days on the road.

And we know that 98% of the time that is NOT how it works…

Sure, on occasion, I will get a UPS ‘next day saver’ shipment from across the USA. Or I will see an Amazon tracking data that shows it is shipping via air from across the country…

But MOST of the time, their algorithm is doing one of three things:

  1. Item is in a local distribution hub- item ships in one day, order by midnight, they transfer it to the local logistics hub at 3AM, and by 1030 it is out for delivery.

  2. Item is in a SEMI local hub- they truck it to the local hub, then it goes out the next day. Here in two days.

  3. Item is far away- it is then shipped via ground transport as a bulk package (no tracking) to my local hub. It shows as not shipped, the order is just sitting- when in actual fact it WAS shipped but takes a week across the USA. Then, after a week, it magically ‘shipped’ and shows up next day.

It is my belief that amazon ‘covers up’ when items really ship… there are two time components to order fulfillment: getting it into a box and out the door AND then the actual shipment. The ‘trick’ of prime is ‘stealing’ a few days from the order processing component and using that for transporting the package- but not letting customers know, so they get their ‘two day shipping speed’

Oh, one marvel: As you are BROWSING- not once you put it in a cart, and not after you pay…but just as you are browsing, the algorithm knows all this an can know how and when they will get that item to you.

Anyway, they can still suck- but insights into how that fulfil orders can explain what we see on our ends…..

August 8, 2023 - Overnight's the fastest I've had. Ordered at 5pm, the truck was there at 8 the next morning. ... Just curious to see if they can get any quicker than an order I placed the other day, which literally took only 3 hours from when I placed the order to when it was delivered. ... Well there is a fulfillment center just 9 miles away from me, so I'm assuming that is the primary reason I can get some stuff that quickly.

r/amazonprime on Reddit: Amazon is flat out lying about Prime shipping being faster
September 14, 2024 -

I cancelled Prime about a year ago. Now I only use it to buy outer record sleeves for my business. Every time I order sleeves they try to get me to resubscribe to get faster free shipping, but it's a scam. Yesterday, the 13th, I ordered $50 worth of sleeves and it said I could pay $6.99 for shipping and get them the 16th, or pay nothing (because my order was over $35) and get them the 18th or resubscribe and get them the 16th. I chose paying nothing and they're out for delivery today, the 14th.
