I've also noticed that if you order multiple items, and one of them has a short shipping time, they'll suddenly ship your other items that are waiting. Presuma

  Flip side is sometimes something that could ship fast ends up being delayed so they can group it with something that comes from a further away warehouse.

    That makes no sense. If you order 2 items, and they're in 2 different warehouses, you'll get 2 packages. They aren't going to ship from 1 warehouse to a 2nd warehouse and then bundle them.

      In my experience, they are (if more economical than sending 2 packages). That is often one reason when it takes long to ship. If you are a FBA seller, you can see these warehouse transfers in the event reports often between a new order coming in ("pending") and the order being shipped. This is obviously more common with slower shipping options - they won't have a lot of time to combine anything with 1-day shipping. I've also clearly seen the difference myself as a buyer between the shipping options - if I select faster shipping, the items tend to ship quicker but they are split into more shipments more often. Also, they may do the same when you order a single item as well - they first move the item to a nearer warehouse and only then ship, if cheaper than shipping directly and if they have the time.
