Despite cost-of-living expenses driving up prices on everyday items, bargains are available on uniforms, electronics and stationary during some back to school sales.

"We've worked hard on our sourcing methods and our internal efficiencies," Officeworks head of stationary, art and education Vanessa Kiel told ACM.

Buying school supplies during January and February ensures parents are getting the cheapest prices, Ms Kiel said.

"You want to stock up now because these will be the most competitive prices of the year," she said.

This could mean buying in bulk for items like pens and glue sticks, with bulk purchasing driving prices down further, she said.

Consider buying in bulk and splitting an order with other parents to keep costs low, she said.

Charity stores are prepared for back to school shopping trips, with quality clothes, shoes, stationary and electronics on offer.

"This is what Vinnies is about, helping people get more for their dollar," St Vincent de Paul Society Victoria head of retail Neil Harvey told ACM.

Back to school displays are set up in St Vincent charity stores around Australia - offering lunchboxes, drink bottles, backpacks and other school needs, Mr Harvey said.

"Our team do a great job of sorting out the quality products," he said.

St Vincent de Paul's offer inexpensive electronics and other school supplies through their eBay portal.

These savings are available to parents around the country, with the online store offering shipping.

"Anyone in Australia can get access to that," he said.

Community members with unneeded school supplies are encouraged to donate locally to help struggling families buy education supplies, Mr Harvey said.

"If you have excess from last year, bring it into Vinnies," Mr Harvey said.
