Can you give your money to Yad Eliezer for Matanot La’evyonim?
Answer:
Yes, it is fine to do so, provided Yad Eliezer has a special allocation of money or goods for the poor on the day of Purim.
For people from un-walled cities, the allocation must be on the 14th, and for those from walled cities, on the fifteenth.
Best wishes.
