WATCH: Summer back-to-school shopping tips
As the back-to-school season approaches, families across the country can take advantage of sales tax holidays to save on essential items.
ABC News' Alexis Christoforous reported last month that school supplies cost nearly 25% more than they did just four years ago, and consumers spent a record $14.2 billion during July's two-day Amazon Prime Day shopping event.

This year, many states are offering tax-free periods for school-related purchases, according to the Federation of Tax Administrators.
These holidays provide a welcome relief for parents looking to stretch their dollars further on clothing, shoes, electronics and school supplies.
"Check if your state is one of about 20 having a tax-free shopping weekend or time period this summer," Christoforous said. "That's a good time to save on pricier items like shoes and computers. Just do a web search for tax-free holidays in your state to find out if and when they're happening."

According to the National Retail Federation, the majority of back-to-school shoppers have already begun purchasing school items.
"The back-to-school and college season is an important time for retailers and consumers," National Retail Federation Vice President of Industry and Consumer Insights Katherine Cullen said in an official press release.
"Families and students are eager to get a jumpstart on their shopping for the start of the school year. Retailers have anticipated this early demand and are well-positioned to offer a variety of products at competitive prices."
Christoforous also highlighted other ways to save, including "Walmart pricing hundreds of its back-to-school items at under 10 bucks and new this year" and Kohl's offering major discounts on Levi's denim.
Consumers can expect more sales on back-to-school items through Labor Day.
