I almost didn't list Swagbucks here because, while it's a great rewards site, they list in their terms that you can't expect for up to 10 days after you cash out. However, it's still an option to earn fast cash because some people report getting paid much faster than this. You can redeem you SB (Swagbucks) for Amazon codes, Paypal cash, and gift cards to popular merchandisers among other things. These points build up quickly thanks the the large number of things you can do on the site to earn. I've used this site and been paid many times.
Pinecone is one of the best survey panels out there for earning fast cash, and they pay quickly — usually by the next day — for the surveys you complete. The surveys don't come every week, but it's a nice little bonus when they do because of how fast they pay. Right now Pinecone is open, but there is no guarantee you'll get in just depending on what demographic they need right now.
Get Paid To Shop: The Shopkick app is a free mobile app that pays you walk into stores, link your credit card, scan barcodes in stores, shop online, refer friends and more. Convert points into gift cards and other cash prizes. This app makes shopping fun, and you even get a 250-point bonus when you sign-up as a new member. The best part? It's 100% FREE to join.
After you sign up for an account, you can start receiving money right away. To use the funds in your account, you can transfer them to your bank account (you will need to add one first). A bank transfer usually takes about 1 to 5 business days. Or, you can request a PayPal Debit Card and have your funds available to use right away. PayPal Debit Cards can be used almost anywhere just like a normal debit card from your bank.
