I have never been an avid shopper for items like clothing and household items, but I like getting new stuff as much as anyone else. I have known about Amazon and other online shopping websites but I was never very active in the past.
Like most people, when I needed something, I went to the appropriate store. You go to your favorite clothing store for those items, to the home store for tools and household items like light bulbs and garden hoses.
Now, with "free" returns, there is no need to worry about making the mistake of selecting the wrong item on Amazon or any other shopping site. Now you can fulfill most of your needs online from shoes to shovels.
This could eventually be a problem for physical brick and mortar stores. They are at a disadvantage in many ways like convenience and carrying enough inventory. It is easier to shop many brands online and select the one you like and just order it.
With that being said, I really hope for the success of stores. Shopping is more than just getting stuff. It is a social experience and one we cannot afford to lose.
