In the USA it might work like that but in some European / Nordic countries a few supermarket chains pride themselves of NOT putting those sorts of things in front of the checkout and help parents to avoid "Pester Power" --and guess what THOSE supermarkets make MORE money !!!
Similarly "BOGOF" offers (Buy one - get one free) sales are hugely discouraged as those just incur people wasting almost unbelievable amounts of food !!!
In some places "Best practices" and Ethical / environmental concerns work better than being as Greedy as possible !!!! -- as I said Businesses can do very nicely indeed by actually treating their customers sensibly.
Ryanair used to be the WORST airline on the planet and had legendary bad customer service -- it even considered introducing a Charge for using restrooms in the plane !!!! -- they changed their policy on customer service and now getting more customers so it can and does work.
As stores are concerned, it all depends on business model. Torontonians would remember "Honest Edd's" store where everything was cheaper but everybody walked out spending more than they planned.
There was a Penny store (later on Dollar) discount store near my place that always had bins with free stuff they didn't have place for to store any more. "Please, take one or we will have to throw it away".
There's no such thing as free.
No such thing.
When you see a sentence containing the word "free", remove that word and you're one step closer to the truth.
I wouldn't go that far. Right now I'm using some really good software that's free/shareware. For example OpenOffice is free and it's very top notch software.
While I agree that "free" is often misleading, one of the absolutely very best FREE apps is Macrium Reflect. For a while, they encouraged purchasing it by providing options like Boot Entry on the hard drive ONLY in their paid versions. But in this recent version, they now offer even that for free.

How did they prove that they make More money?
Edit: Buy one, Get one free is not the same as Buy one get second one at a discount.
