One pick-up card in kindergarten costs 30 yuan, and two more are needed. Is this reasonable?

Going to the Education Bureau won't help much. I suggest you complain to the local price department. You can call 12358 directly, but you'd better find someone to complain. Never complain to your face, and don't wait until your child graduates, otherwise it will affect your child's life and study at school. It doesn't matter if you complain within two years. It's effective. .
