Banks make way more in interest and fees from borrowers than they do from merchants. The "rewards" for rewards cards are largely funded by fellow card users who carry a balance and therefore pay boatloads of interest.
That would be called "their mistake". I can empathize. We made those mistakes 20 years ago and it took 7-8 years to correct them. Running any sort of a balance that draws an interest payment to a credit card company is simply that, a mistake.
Only person I ever saw play that game and win, was a friend who remodeled his house on a card and sold the house three month later in a very up market. He returned way more value than he paid interest on. He'd just been through a messy divorce and could t qualify to do it with a traditional home equity loan. He was also a realtor and knew exactly what his timeline and prices were going to be.
But I can't say I'm not thankful for everyone still making that mistake who's paying me thousands back every year. Rough. I know. I paid for somebody else's once.
If there's one piece of advice for anyone just starting out that I always give, it's that if you can't figure out compound interest, and how much money it will cost you, life is going to be very very hard for you.
You support them with higher prices than if credit cards never existed. The merchant pays a percentage of the charged amount as a fee to the banks. Anywhere from 1 to 3 more percent of the total. Those costs are built into the prices you pay.
Yup.
But, except for a few gas stations, the price is the same whether you pay with a credit card or not.
Becoming way more common than you think. All of the grocery stores are doing it here now along with their "points" thing for cheaper gas prices. Watch the price numbers on the pump carefully compared to what's on the sign next to the road.
Also seen it at two other national brand stations recently here. The pump flips the price depending on which type of card you insert.
Debit gets cash price, lowest. Credit is higher. Watch for it.
Apps like GasBuddy had to add fields for cash vs credit prices into their backend database and their apps for reporting fuel prices.
I rarely use the app, it's almost never worth driving extra miles out of your way for two or three pennies on a gallon, unless I'm filling the diesel, and even then it's not going to usually amount to much more than a buck with a 35 gallon tank.
But the stations are scraping additional pennies these days for credit purchase.
Usually where I use the app is on road trips. Often stations located right at the freeway exit are $.20-$.30 higher than ones a mile off the highway. If the truck and the fifth wheel will fit under their awning, saving $10 is worth a half a mile.
At one highway exit along I-80 we saw a $.50 difference between the truck stop and the in town station only three blocks up by looking on the app. "Highway robbery" is real.
