Amazon is moving to what it calls Frustration-Free Packaging:
The Frustration-Free Package (on the left) is recyclable and comes without excess packaging materials such as hard plastic clamshell casings, plastic bindings, and wire ties. It’s designed to be opened without the use of a box cutter or knife and will protect your product just as well as traditional packaging (on the right). Products with Frustration-Free Packaging can frequently be shipped in their own boxes, without an additional shipping box.
That last sentence points to one potential downside:
Frustration-Free Packages ship in their original boxes, without an additional box for shipping. If you want the contents of your package to remain a surprise to the recipient, you should select the ‘Gift Wrap’ option during check out. Your gift-wrapped package will be sent in an additional Amazon shipping box. If you include a gift note but not gift wrap, your package will ship in its original box and the contents may be visible to the recipient.
Anyway, the folks at Amazon clearly “get” logistics.
