4 Phone Calls That Can Save You a Ton of Money

— -- intro: With late fees, penalty interest rates and complex credit-scoring algorithms, it often feels like the world of personal finance is designed to be unfavorable to the consumer. As challenging as it may be to keep everything in order, there are plenty of things about your finances you can control, even when it seems like someone else is calling the shots.

If you're looking for ways to save money, start asking questions. Can you qualify for a credit card with better rewards than the one you have? Would a different cellphone carrier give you the same service for a lower price than what you're paying now? Researching alternatives is always a good idea if you want to change your expenses, but you may be surprised how much power you have in your existing relationships. Sometimes, all it takes is a phone call to save money.

The worst that can happen is you get turned down and have to pay the fee, but you'll definitely have to pay if you never ask for an exception. If you're regularly late with payments, you might want to also shop for a credit card that doesn't have late fees or forgives late fees for good customers.
