I'm not from the United States, so forgive me if I don't understand how Amazon works. But does this system imply that orders through this system will be delivered in individual mail packages, with delivery fees paid (either explicitly or implicitly) for every package? When a normal human makes an order, she will group several items in one delivery package most of the time. Especially for the inexpensive and non-urgent stuff like the laundry detergent. Will it cause more wasted packaging materials and more fuel spending overall?
