As a child from age 4-9 I used to put my pocket money in the donation box. But this was the late 80s and early 90s so it would only have been about 50p.
After than I donated sparingly. Not very much at all. Like pocket change.
when I moved out of my parents home I never donated a thing. At the time I felt a little guilty about it but looking back I'm so glad I never put any of my hard earned cash in there.
