Question:
If I recite Yizkor, can I simply put a certain amount of money in the pushka after Yom Tov?
Answer:
If you didn't specify that you were going to give the yizkor money to a specific tzedakah, you can give it to any tzedakah. The yizkor money is given as a zechus for the niftar and any good cause will be a zechus for them.
