The Shaarei Teshuvah (625) writes: “It is proper to give a lot of charity on erev Succos.  Reb Chaim Vital would distribute the tzedakah pushke to the poor on this day.”

Rebbe Chaim of Tzanz said that there isn’t a nicer succah decoration than the tzedakah that one gives on erev Succos.”  ~ R’ Elimelech Biderman Shlita
