The first time I wanted to order at Amazon I waited until I had 5 items I needed. I could have saved myself the trouble because these items were delivered on several days by 4 different deliverers. And the amount of plastic I had to throw away afterward was HUGE.
Instead of complaining, being wiser after some eye-opening conversations I had with businesses about customer service, I decided on my own strategy to reduce packaging: “I used my feet” and searched for more environmentally aware shops.
