the point of these drives is to get more people to give to charity. Then you use a lullaby-word as if setting up a charitable donation is as easy as saying "yes" when the checker asks if you want to give a small donation.
You're overthinking this. There's a publicity element to it, but the money just gets given to charity, like they say it does. It's not a conspiracy or a tax accounting trick.
Same way I can tell that my next door neighbor isn't poisoning my water supply or that Tesco doesn't have a secret chemical weapons program. That major supermarket chains are running scam charity appeals just isn't a hypothesis worth entertaining in the absence of any evidence for it.
Agree - I don't think a giant multinational should get the cumulative charitable donation through their "Gavin Belson Foundation", and frankly it coming while you're checking yourself out, and navigating all dark-pattern "share your email for an e-receipt?", "want our deal of the day?", "enter your loyalty card?", "fill out this poll?", "are you collectioning stickers?" nonsense really grinds my gears. I just want cheaper groceries!
