It is one of two book sales the charity holds annually, with the other at UWA.
University branch president Anthea Fellowes said there would be about 7500 books for people to browse.
“There are books for everyone at great prices and most importantly, the money raised goes to children in need here in WA, Australia and overseas,” she said.

“We are delighted that we can bring this massive book sale to Joondalup, sell good quality books at great prices, and also spread the word about the work Save the Children does.”
Ms Fellowes said they were hoping to raise more than last year’s total of $12,000.
“Seventy per cent of funds raised will go to programs here in WA in areas like Armadale, Gosnells, Kununurra and the Dampier Peninsula,” she said.
“The remaining funds are distributed to other programs run by Save the Children in Australia and across the world.”
The sale is at Arena Joondalup on Saturday, 9am-4pm, and Sunday, 9am-1pm.
