SAN ANTONIO -

Shoppers can save roughly $8 for every $100 they spend August 17-19 over Tax Free Weekend. The sales tax holiday happens every year just before students head back to school.

Fighting crowds and long lines is the price you’ll pay to save on Tax-Free Weekend.

Yariza Colon, a mother of two daughters, took the day off Friday just to beat the crowds in the school supply aisles at the HEB Plus in McCreless Market. It’s her first time shopping on Tax-Free Weekend.

"You know, everybody's out shopping for a little bit of everything,” she said. “So I thought I'll try it and see if it saves, and if it does, I'll do it next year on Tax-Free Weekend."

A piece of advice before you shop: Know your game plan.

“Have your list ready,” said Elisa Guttierez, store director at HEB Plus. “We have the store segmented so if you needs craft stuff we have the construction paper and glue in a section. Or if you need writing utensils, we have all the pens and pencils together."

You can buy school supplies, clothes, backpacks and shoes tax free through Sunday. Each item must be under $100. If you buy an item that costs more than $100, you will pay tax on the full price.

For example, if you buy a $105 pair of shoes, you will pay tax on the $105, not just the $5 difference.

The state comptroller expects Texans to save roughly $65 million this weekend.

Even if you're not headed back to class, nothing teaches patience like tax free weekend.
