Look up "there ain't no such thing as a free lunch" from Robert Heinlein.
Generally speaking, if you're getting given something, there is some sort of mechanism by which the card issuer is going to get more than the thing they are giving you. Otherwise they wouldn't do it. Sometimes they will offer incentives where you can actually make some small profit, because they want to bootstrap the usage of some new service by bribing people to use it for their real-world big transactions. But that will generally stop as soon as the new thing is established. Sometime they will give you a piece of some cut that they're getting (they charge 3% to the merchant as a processing fee, then they give you 1% in rewards as your cut, so you'll use the card more and their 3% will be higher). But, in general, you won't really be able to beat the house by more than a miniscule amount.
They're looking to bring money in, not give it away to you.
Yeah, but these are also sometimes a numbers game. For example, rewards credit cards can offer their rewards because they make more than what they are worth in interest + annually fees for the cards. It is possible to make this work for you if you never carry a balance on your card, and make back some amount > the annual fee.
You’re right though, these companies aren’t just giving money away for free. You have to be very strategic to make these things work in your favor.
That’s not precisely true. Generally, the rewards are paid for out of that 3% merchant fee that they take in. Usually if you do the math, the rewards will always add up to a healthy chunk below that number, being high enough to be attractive, but low enough that they’ll make a comfortable profit no matter how much rewards they wind up paying out. As you noted a lot of people use their cards in a way where they make way more in rewards than they pay in interest and fees.
Yeah. Especially if you find new services that are trying to run at a loss to get going. I don’t have specific ideas for an answer to your question but that’s where I would try to look: Some just-launched service or paradigm that’s having to bribe its customers to build up interest (of both varieties).
