A trip to the mall can often be more overwhelming than balancing your checkbook at the end of the month. (Will we ever learn to just do it as we go?) With so many options and price points, it’s difficult to know what any one item is really worth. Typically speaking, I like to keep all purchases under $100. And if I’m being honest, I have a hard time shelling out more than $50 for any one item. But rather than look at the price tag as a single number, I’ve actually found the best deals (and saved the most money!) when I’ve employed a simple formula: cost per wear.
