Back to school season can be as expensive for parents as it is exciting for students. Once the initial letdown of the end of summer vacation wears off, many kids are excited to return to school, where they can see their friends, study their favorite subjects and participate in extracurricular activities.

Parents of school-aged youngsters may share in that excitement while also knowing that back to school season can stretch their budgets. One of the ways to salvage those budgets is to save on school supplies. Fortunately, there are several ways parents can do just that.

• Be patient. Shopping early can save shoppers money in many instances, but parents may benefit by exercising patience when it comes to buying school supplies for their children. Teachers often give students lists of supplies they will need for each class, and parents who wait to receive such lists can avoid spending money on items their kids won’t need. Even if you wait it out, you may be able to get a head start, as some teachers may post supply lists on school websites, while others might email lists to parents before back to school season hits full swing.

• Take inventory. If you have more than one child, chances are you already have lots of school supplies around the house. Dust off kids’ backpacks and study areas from last school year to determine which supplies you need to buy and which you already have. Going forward, encourage kids to store their supplies in a predetermined area once the school year ends, as this will make next year’s inventory that much easier to examine and assess.

• Spend more now to save later. While inexpensive supplies can be hard to resist, such items likely won’t withstand the test of time, forcing you to spend time and money each year buying replacement supplies. Paying more now for certain items, including stronger backpacks and more highly rated calculators, may end up saving you money in the long run, even if the initial pill is somewhat tough to swallow.

• Use technology to your advantage. Department stores and businesses that sell school supplies, such as pharmacies and office stores, may or may not discount too many items once back to school season hits full swing. But savvy parents can still find deals by using technology to their advantage when shopping for school supplies. Download apps like RetailMeNot to your smartphone and enable its updates so your phone essentially notifies you of any discounts the moment you walk into a given store. If you don’t receive any updates, search for discounts via the app or the Internet as you shop. Chances are strong that there are deals to be had, even if you don’t learn of the deals until you arrive at the store.

School supplies can be expensive, but parents can employ several strategies to save on school supplies now and in the future.
