I bought lots of stuff. I use to buy anime when I was younger for to watch with my younger brother. Also, when my car was in the shop for a good amount of time, I bought a lot of books. Games are a good buy. My brother buys things he can't find at stores, which happens quite often. I use it to buy gifts for the family. And it can help when you want to get something, but you are running low on free time. My mom uses it for all kinds of stuff to help my sister with her many extracurricular activities... I think it depends on the things you want and lifestyle. Personally, it works very well for my family. Also, Prime video was good for watching at work...
Well yeah but I meant for an average person. Amazon is good for harder to find stuff but even books on there can be expensive. ---
