HOUSTON (KTRK) --"Last year I spent like $300 just in supplies," said parent, Maria Olivia.
Maria Olivia is buying school supplies for two kids and it's important she stick to a budget since she has a baby on the way.
This weekend, she's getting a bargain, though, by getting school supplies and diapers tax-free.

She hit the store early on Friday at the start of tax-free weekend.
"I came in here real early before everybody gets here," said Olivia.
It wasn't just parents shopping for supplies. We found many generous people in the aisles buying supplies for other kids headed back to class.
Holly Romero's company is buying 90 stuffed backpacks for inner city kids.
"When you're blessed and you're given the opportunity to have a full time job and care, or are just blessed, in general it's a joy to give back," said Holly Romero.

Retailers also see a boost in sales, too.
This year, the National Retail Federation says consumers will spend more than $75 billion on back-to-school shopping.
While this weekend benefits moms like Maria, people giving back, and retailers, there's been a push to end the tax-free weekend.
"This matters to everyday Texas and we ought to do as much as we can to expand it. I know it's going to be tough with budget issues when the legislature goes back in session, but I'm going to do as much as I can to protect this holiday because it matters to so many people," said Texas State Sen. Rodney Ellis, a Houston Democrat.
The tax-free weekend costs the state $90 million in revenue a year, but it's a saving for so many others who plan for it all year long.
