I know a few that never buy a new thing/product and always go for a used product and actually they cannot afford to buy a new product and have been in the habit to buy used products only and smart enough to choose the best product that delivers for a long time and this way they are saving a lot of money.
They are buying smartphones, LED TV, even Bike and car, because if you go for used products then you can save even 50% even if the product was used for a few month only
