Infused water
Water with vitamins, minerals, flavoring and maybe even “sugar alcohols” can run as much as $3.50 a bottle, according to Cheapism.com.
However, the website says, “the health claims about nutrient-enhanced water are largely unsubstantiated. The synthetic vitamins probably don’t provide the same benefits as vitamins found in a healthy diet. Plus, many fancy waters contain large amounts of sugar.” Instead, Cheapism suggests, you should bring your own water from home — and if you like, toss in some fresh fruit.
