Sheree Woods is sitting in her car in the parking lot of a mini-mall in a Los Angeles suburb, with the air conditioning blasting.
She's here for a huge sale.
Woods is a high school art teacher at Sherman Oaks Center for Enriched Studies, a big magnet school in the Los Angeles Unified School District. Every year, like countless other teachers around the country, she digs deep into her own pocket for school supplies.
"I would say between $300 and $400 is a pretty average year for me," she says. "Sometimes it's a lot worse, but don't tell my husband!"
Woods notes that she's a veteran teacher, and so she has a lot of extra supplies in her storeroom from years past. Younger art teachers sometimes spend much more than she does.
Sheree Woods, an art teacher at Sherman Oaks Center for Enriched Studies in Tarzana, Calif., hopes to spend less than $100 on this shopping trip for art supplies for her students.
Art teachers have to switch between classes like painting, ceramics or print-making, Woods says, and each has a different list of supplies: glazes, acrylics, X-Acto knives.
Inside the store, Woods works the aisles, carrying a plastic shopping basket.
After decades teaching, she knows good prices by heart. She calls herself the "coupon queen." But she also knows she can't scrimp on quality.
"I really believe that the students' work, the quality of their work, will go up with the quality of their materials," she says. "So it's worth it for me to spend a little bit more. Just for those two-dozen pencils it could cost me $20, $25. So I'm hoping to get out of here today (spending) under $100."
She stops in the aisle and points out colored pencils that cost $1.84 each.
It's more than she'd like to pay, but her students need these pencils to learn the fine points of shading.
Woods grabs a handful of greens and browns, tears off a paper coupon, and heads off to look for pencil sharpeners.
