I’ve noticed that Amazon has 2 ways of deliveries -
Sellers use Amazon: there is a symbol saying "a" called amazon fulfilled. this has amazing packaging and delivered from amazon warehouse. I made 3 orders and surprised looking at the packaging. "Amazing Amazon".
Direct Sellers: they ship your products after you place an order. They are doing decent but there might be a slight delay in delivering. But you can negotiate with them and get it delivered on time.
