On the flip side of the coin is the consumer. If you could save a dollar on every financial transaction you made every day, you could end up saving a boatload of money over time.
Impossible to do? Maybe. Maybe not.
When you fuel up the car with gas, can you save a dollar? Maybe by buying a car that burns regular instead of premium. Maybe driving more carefully and getting better gas mileage. Maybe by buying a car that gets better gas mileage as well.
Note that I didn't say, "getting a 1% cashback rebate on your credit card rewards" or "shopping for gas that is a few pennies a gallon cheaper" as both end up saving a lot less money than the solutions set out above.
When you have lunch every day, can you save a dollar? Well, if you bring your lunch to work, you can save a few dollars as it costs about 1/2 to 1/4 to make a meal at home than to buy one.
Note that I didn't say to use coupons or order the special at the restaurant, as these techniques really don't save as much.
And so on and so forth. The marketers and businesses want you to spend more, of course. And often, we do, without thinking. Or we think, "Oh, it's just a dollar, right?"
