5. Take advantage of hidden discounts

When buying online, check to see if the store is offering a coupon code. "There are literally thousands of sites that list coupon codes," said Kim Danger, founder of Minnesota-based Mommysavers.com that helps parents pinch pennies. "A simple Google search using the store name and coupon code will help you find current codes." Be sure to take into account shipping costs and taxes, she noted, and research the store's return policies.
