If you have an old smartphone and you need money today, check out ecoATM. Type in your ZIP code, and with any luck, you’ll find one of their ATMs in your area. If you do, you simply find the kiosk and place the old cell phone in the ecoATM’s test station, where the machine will examine your phone — noting the model number and condition, among other features. It then automatically scans the resale market for similar phones and offers you a price based on its value — if you agree to the price, you’ll get the money on the spot (hence the ATM in the name). They also accept MP3 players and tablets.
Beg or panhandle. When all else fails, you always have the option of simply asking for money. If you do this, you'll probably want to do it on a busy street or some other safe public place that receives plenty of pedestrian or car traffic. You might actually be able to make a decent living by panhandling, although it will require many hours of your time in potentially unfavorable weather conditions.
Open an Etsy store. If you have a creative talent or skill – whether it’s creating art, sewing clothes, or making keepsakes – you can open an online store on Etsy.com and sell your wares for some quick cash. With your own Etsy store, you’re left in charge of pricing and, ultimately, how much you make. See our detailed primer, “How to Make Money on Etsy.”
A large subset of our society is earning a full-time income by selling items on Craigslist and Ebay. You can do this by selling your own items, or you can help sell items for other people and take a small commission. Selling on Ebay offers more friction than Craigslist and you'll need to establish solid reviews before you can begin to move high-ticket items.
I recently stumbled on the Trim app and I have to say, this one is a game changer. It’s a simple app that acts as your own personal financial manager. Once you link your bank to the app, Trim analyzes your spending, finds subscriptions you need to cancel, negotiates your Comcast bill, finds you better car insurance, and more. And of course, the app is free! My bet is that it will only take a few days for Trim to put an extra $100 in your pocket. So easy!
