From what I see people tend to shop brick and mortar for things that they enjoy shopping for, and at places where the shopping experience is enjoyable. Going to the friendly local game store is an experience. The local store in my neighborhood hosts gaming nights, and scavenger hunts, and all sorts of nice things. These types of brick and mortar stores are still successful.
But buying toilet paper, towels, and other random supplies is not a fun or enjoyable experience. There is nothing fun about going to a big box store, walking down crowded aisles, loading up a rickety, squeaky cart, and pushing it to a checkout lane with a long line. No one likes going to the store to shop for boring stuff so Amazon delivery is a clear winner there.
But brick and mortar isn't going anywhere. It will always continue to be successful for sales that are actually fun and enjoyable things to buy.
