Tax write offs would be my guess. Every employee of charities that partner with retail locations for PoS donations must die a little inside each time some fool confidently asserts that they never give to those charities because it's all a scam. The money, they will assert with the confidence only someone so wrong can muster, is just used for write offs so the executives can have a big bonus and the company gets to claim they donated all the money. Bonus points if they assert that the charity doesn't even get the donated amount.
