When Mcd's first started running the Happy Meals/Proceeds donated spots, I emailed them, asking how much money is donated per meal. Their quick response: that participation varies depending on the owner of any given franchise, so they couldn't provide a figure. I wrote back, asking, surely there's a minimum percentage? They didn't respond to the followup. Hmm. But even I was suprised to eventually learn, while reading the fine print myself, that it was only one penny per meal!
