Utilization of an online shopping, Amazon

I tried to utilize an online shopping service, Amazon. Although I have used this system several times in Japan, I did it many years ago. I basically don't like online shopping services because I don't want to wait for something delivered in my room. I don't like to stay at my room for a long time with waiting something. However, a reason let me determine to use this system currently. I notice that some boxes sometimes delivered from Amazon are placed on the mailbox in front of my apartment, which means that shipping agencies deliver their goods in the mailbox, not in our rooms. This means that we don't have to wait for the goods in our rooms. That is why I determined to use Amazon.
