If you spend a lot at Amazon.com, for example, you can get a card that rewards you with 5% cash back on Amazon purchases -- which can really add up. Stores such as Target, Costco, Gap, Lowe's, TJX, and Wal-Mart also offer cards. Plenty of retailer cards offer 3% to 5% in cash back or discounted prices and many offer other perks, too, such as free shipping. If you travel a lot, travel-related credit cards can help you rack up lots of points and rewards that can be used instead of cash, keeping more cash in your pocket.
If you’ve got some free time and don’t live in the middle of nowhere, becoming a Lyft driver can be a very lucrative side hustle that allows you make money fast. And right now, they’ve got a promotion going on where any new driver will instantly get a $300 bonus after completing their 100th ride. If you start now and hustle hard on the weekends, you can probably unlock that bonus within a few weeks of driving (and that’s in addition to your normal earnings).
