Why Do Companies Give Away Free Products?
I just got a freebie, so I'm just going to write about this.

Last week a stranger handed me a tiny cup of iced coffee outside a mall, and twenty minutes later I was holding a full-size bag of the same beans I never planned to buy.
That’s the whole strategy working on me in real time. Companies hand out free samples because it’s cheaper than advertising and far more effective, since once you’ve actually tasted or tried something, it stops being an abstract pitch and starts feeling like your own decision.
There’s also a quiet psychological pull called reciprocity. When someone gives you something, even something tiny, you feel a small itch to give something back, and the easiest way to do that is to buy.
Then there’s customer acquisition, which is just a fancy way of saying it costs money to find a new buyer. A free sample or a free trial is often the cheapest route, especially when one converted customer will spend far more over time than the sample ever cost. Apps do it with free tiers, streaming services do it with trial months, and most of them are betting you’ll get used to the product before the bill shows up.
Is it manipulative? A little, but it’s also a fair trade, since you really do get something for nothing if you can walk away.
So take the free stuff, just know it was never really free.
