Hamodia published a great letter this week from someone who is annoyed that he is being inundated with all kinds of useless free stuff from צדקה organizations. As he says "I don't need prizes to give צדקה".
I wholeheartedly agree and would extend this to all of the historic events as well. I don't need prizes and I don't need historic events to give צדקה. Give people a little credit that they give צדקה for the right reasons.
Here is the full text of the letter.
