To Purchase this Sefer 
The organizations and individuals which collect Matanos Laevyonim to be distributed on Purim, may not use any excess moneys they received for other charitable purposes. Rather all the donations must be distributed to paupers. However the paupers themselves may use the money for whatever purpose they choose. [Thus they may use the money to buy any item for anytime, and they do not have to use the money specifically to buy food for Purim.]

 See M”A 694/5; Kaf Hachaim 694/32 that some Poskim rule although the collectors cannot change the use of the money nevertheless the community has the power to do so.
