It's remarkably easy to overspend.
Not only are we surrounded by enticing things to buy, but they're at our fingertips with the swipe of a plastic card, leaving us with thinner wallets and a bunch of unnecessary stuff and services.
Here are 15 things you can stop wasting your money on today:
1. Cable TV
With the advent of Hulu, Netflix, Amazon Instant Video, and Apple TV, there's hardly a reason to splurge on a fancy DVR system or even basic cable — so long as you're willing to be patient.
Most shows are added at least 24-hours after airing and some networks won't give them up until eight days.
2. Bank fees
Banks love to slap you with fees at the drop of a hat, but that doesn't mean you've got to put up with it.
"If you travel abroad often, make sure you use credit cards without foreign transaction fees, otherwise you'll be paying an extra 3% to 5% on all your purchases."
3. Extended warranties
Retailers push hard to sell you extended warranties — and conveniently pump up their sales figures at the same time.
Don't do it, Schrage warns.
"The only instance I'd recommend a warranty is in the case of a laptop. Otherwise, the warranties themselves can often cost as much as simply buying a used or new replacement for your item, or repairing it," he adds.
4. The roof over your head
If you're blowing most of your income on a loft in Midtown, you're making a big mistake, says Jeremy Gregg, executive director of the PLAN Fund.
His organization provides loans to low-income entrepreneurs, who Gregg says he often sees spend more than half their income on rent and utilities.
The U.S. Department of Housing & Urban Development recommends spending less than one-third of your income on housing.
5. Unnecessary smartphone data
"Many of us (including me) pick a cell phone plan, then never check to see if it's the right one for us based on our usage," writes author of "I Will Teach You To Be Rich," Ramit Sethi. "Because the average cell phone bill is about $50, that's $600 per year of money you can optimize."
When buying a new cell phone, Sethi likes to pay a little bit more upfront by choosing the unlimited data and text messaging plan. He then sets a three-month check-in on his calendar, and analyzes his spending patterns after a few months to see where he can cut back.
You can use this method for any usage-based services, he says.
6. Online shipping
Nearly all retailers offer some sort of option that gets your purchases to your doorstep without additional fees.
To help track down deals on shipping, use Freeshipping.org. The site stores information on expiration dates, tells you much to spend to qualify, and lets you search by store name or product.
7. Cheap art
Environmental designer Pablo Solomon says picking up knockoff prints and other art is a great way to blow cash for no good reason.
"Nothing sends me through the roof like the art sold on cruise ships and at resorts," Solomon says. "(They're) basically glorified posters being sold as originals."
The best way to score deals on art is to track up and comers, he says. You can nab their art early on and laugh your way to the bank after they've made it big.
8. Fast food
You're only hurting yourself (and your wallet) if you're feeding yourself out of the bodega around the corner from your home or office.
"I am shocked at how many people live paycheck-to-paycheck and yet routinely spend $10 per day on fast food and convenience store food," Gregg says.

9. Piecemeal insurance
Buying overpriced insurance for things like accidental death and diseases is an easy way to blow your funds.
"Instead of buying piecemeal insurance policies, get good term life insurance and disability insurance," says Sally Herigstad, a certified public accountant and Creditcard.com columnist.

10. Lousy gifts
Personal finance expert Dani Johnson suggests you think twice before rushing out to buy Dad another tie this Christmas.
"You should make a pact with your friends and family to give back instead," Johnson says. "Pool a percentage of money you were going to spend on gifts and give a secret blessing to somebody who is truly in need."

11. Weight loss traps
Weight loss pills and supplements marketed as miracles for overweight couch potatoes are most likely traps.
"Not only are there enough pills and potions that you could start a new one each week, but the negative effects on your health outweighs the money you will waste," says nutritionist Rania Batayneh.
"This is a billion dollar industry and the truth is that a lean body does not come in a pill," Batayneh says.
12. Lottery tickets
"Sure, you can (buy a lottery ticket) every once in a while just for fun, but never make a lottery purchase with any real expectation of winning," Schrage warns.
"The odds are significantly stacked against you, and why waste your hard-earned money on lottery tickets when you could be saving for retirement or treating yourself to a nice meal?"
13. Brand new cars
"People get bored with cars quickly. They always want a new car and so they're always dealing with a car payment," says certified financial planner Michael Egan. "But it's a hugely depreciating asset. You don't want to be putting a lot of money into something that's going to be worth nothing after a certain number of years."
Another option is leasing a car. You can determine whether or not this is a good option for you by following this flow chart.
Subscriptions — to magazines, newspapers, and the gym — can add up, and oftentimes, we don't use them as much as we had originally planned.
Sethi recommends implementing what he calls the 'à la carte' method, which takes advantage of psychology to cut our costs.
"Cancel all the discretionary subscriptions you can: your magazines, TiVo, cable — even your gym," Sethi explains in "I Will Teach You To Be Rich." "Then, buy what you need à la carte. Instead of paying for a ton of channels you never watch on cable, buy only the episodes you watch for $1.99 each off iTunes. Buy a day pass for the gym each time you go."
It works for three reasons, Sethi writes: You're likely overpaying already, you're forced to be conscious about your spending, and you value what you pay for.
15. A morning latte
Author of "The Automatic Millionaire," David Bach, coined the term, "The Latte Factor," which basically says that if you ditch your $4 latte every morning, you'd have quite a bit of money to contribute towards savings — about $30 a week, or $120 a month). Over the course of a few decades, that money could grow substantially.
Rather, invest in a nice coffee maker, even if the price tag is a bit steep. Oftentimes, spending more on high quality items can help you save in the long run.
It can seem counterintuitive to make purchases to save, but that's what some of the most successful money-savers do. They're not just buying things, they're investing in things — tools and services — that will eventually save them money over time.
