Because of the way i structure my paychecks (receiving 26 a year but budgeting as if i only get 24) there will be two months where i get three paychecks. I still plan to donate 5% of my income, so this month equates to $153 as opposed to $102.
I went with a "Maslow's Hierarchy of Needs" theme here (as i've done in the past), focusing on the bottom rung:
Euclid Hunger Center - $51 - food
Greater Cleveland Habitat for Humanity - $51 - shelter
Charity: Water - $51 - water
