Thinking about buying something, planning to buy it, allocating the some money or savings for that purchase doesn't necessarily mean that you need the item/product, etc which you want to buy. A number of people when they get to that point when they must hand over the money start thinking . . . do they badly need that item/product? Can they do without it? What should one do if they are in such a situation? Buy what they planned? Best thing to do when doubts assail you is this — don't buy what you planned to immediately. Go home or get off the site if you were buying from an online store. If after one week you believe you need the item you wanted to buy then go ahead and buy it. How do you guys deal with this sort of stuff?
