It’s pretty common for there to be a ‘minimum advertised price’ (MAP) where a brand can cut retailers off if they advertise a price below it - this is why so many stores will have the exact same price on a given product and why you’ll sometimes see the ‘lower price in cart’ message.
It sounds like the issue here is that Walmart managed to get Energizer to have a higher MAP price, but I’m not sure how much more collusion-y that is than MAP prices in general.
