"Kinda like how Black Friday is the beginning of the holiday shopping season, Missouri tax free weekend is the kickoff for back to school shopping," said Aaron Byrd, General Manager of the St. Joseph Best Buy.
With just a few weeks to go until kids head back to school, some parents took advantage of no sales tax.
"Whatever we can save helps," said Ronda Stout, a grandparent of kids in school.
Stout spent the afternoon helping pick out school supplies for her grandchildren.
She says the supply lists are much different than they used to be.
"When we were buying them for our kids, we had just pencils and notebooks and not a whole lot," she said. "And now they want so much more, bigger notebooks, rulers, high-tech calculators, stuff like that."
At Best Buy in St. Joseph, General Manager Aaron Byrd has also seen the change.
In recent years, electronic stores like Best Buy have had more back to school shoppers.
"The tablets have become such an integral part to the educational process, it seems like that that's a really big scene for us," said Byrd.
Byrd says this year some local schools have even added headphones to their supply list.
"They can put it with the tablets so that the kids can listen to that kind of educational stuff," he said.
And Byrd says tax free weekend is the time that many parents and students take advantage of the savings.
"We gear up, we bring in additional people, we staff additionally," Byrd said. "We bring in additional products like MacBooks, additional laptops that we may not carry the rest of the year because we know there are people that will come in and take advantage."
