Back-to-school shopping can be expensive, but there are ways to save money. Sales tax holidays are offered in many states, allowing shoppers to save anywhere from 2-7% off their purchases. It's important to know when the tax holiday starts and stops, and what items are tax-free in your state. Shopping online is also an option, as most states allow for tax-free online purchases during the holiday period. Other tips for saving include determining how much you can spend without using a credit card, making a list of what you need to buy, and sticking to the plan.
