Impulsive buying

Do you notice that whenever you buy something and you thought you were able to save because of the discounted price, it will turn out that it is more costly in the long run? I have made impulsive purchases in the past. Cheap purchases that turned out to be more costly when I sum up the repairs and eventual replacements I made. Not as expensive as Ferrari parts, yes, but still costly for someone like me. So be careful with your purchases.
