Amazon's fulfilment has also become shockingly bad. Most items are shipped in lightly-padded manila envelopes resulting in high percentage of damaged goods if you order books[1], CDs/DVDs/BluRays, video games, or anything else where the packaging is part of the product. eBay is a much better experience in this regard. [1] In an ironic twist, I absolutely refuse to buy books from Amazon anymore.
On the other hand, I received a $12 box of wet wipes that came in a giant, nicely padded box. The product itself was in a sturdy box. $400 dollars worth of computer storage was shipped improperly, but Amazon made sure I got my box of wet wipes safe and sound!
More often than not, I receive small items in giant boxes. Amazon used to ship one order in one box, now they ship one order in many boxes.
I don't know how much waste Amazon generates with lazy packaging, but it must be a colossal amount.
