Is shopping a sick pastime? Or is it just 'normal' and harmless because so many people spend time doing it?
I don't know what to answer to your question, and I don't think it is directed to me. I have never been a shopper, I don't understand shopping as a pastime, sometimes I have to go and buy necessities, and if I can avoid going to a store, I will certainly chose to do it.
As to shopping online, I don't do it unless, as above, it is to buy something that has become needed.
