To get coupons for children's museums, check the discounts section of the museum's website. You may also find coupons by performing a search for the museum at Coupons.com, as of July 2015.
Discounts vary based on the museum, but a museum typically lists any available discounts on its website. Discounts that children's museums may offer include military discounts, teacher discounts and discounts for people in low-income programs. Certain museums also offer free times, during which admission is free. Free times usually occur weekly or monthly and last for a couple hours during the day.
If you visit a museum frequently, purchasing a membership at that museum offers another way to save money. Children's museums may offer family memberships.
