Items that you buy more commonly end up costing you a surprising amount of money -- often more money than big, expensive items that you buy only once in a while.
For instance, the 55" TV that cost you $1000 is effectively cheaper than a $2.45 coffee if you buy that coffee every day, but keep the TV for two years.
$2.45 (cost of coffee) X 5 weekdays in a week X 52 weeks in a year X 2 years = $1,274
