9. Clothes
Like makeup, clothes are amongst the most marked up items when it comes to their sale value. Designer jeans, for example, can often be marked up more than eighty percent from what it actually costs to make them, while sneakers might only cost $15 to make before being sold for in excess of $70.
You can easily save money on both clothes and shoes by shopping sample sales, using Chrome extensions to find the best coupons, or even buying gently-used items online at places like eBay.
