She says giving people a chance to get a bargain is always good and it is usually a fun day.
"It's fun, full of bargains, supporting a good cause and there will be cake."
Goodie bags will be given to the first 200 people.
Olive says the centre is run by a committee of volunteers and the committee has decided to put all funds back into the centre this year.
Last year, funds were donated to the Rotorua Car Seat Clinic.
"There are many things the money could be spent on, but most likely will go on updated resources for our antenatal classes and professional development for one of our lead childbirth educators.
"Every bit helps to ensure the centre continues to run and provide the community with quality advice, information and support."
She says having this support available is important because parenting is hard.
"Parents need to know the basics of looking after their children to provide quality and necessary care.
"They also need to go into the journey of parents as informed individuals."
