I dont know anything about this event so what I am posting is just conjecture.
If it is some sort of summer Tzedakah event because there are only so many sundays in the summer its tough and its worse this year with 17 Tammaza and Tisha Bav being on a Sunday along with a Sunday during the 9 days. 3 Sundays are lost (Sundays are the best days for a fundraiser). There are other origanizations doing fundraisers too so needed funds might not get collected.
So they must have gotten like some sort of Heter like a Siyum or something to get permission for this fundraiser
