Selling blood….there are very few companies that buy your blood. #1 reason being MANY people willing to sell their blood are not the type of people you want to receive their blood, ie drug addicts (not everyone). And if you can find a company willing to buy your blood you can only give it every 56 days (for whole bood). The most common blood product that is bought is plasma and you can only do that every 28 days (in New York state …which won’t buy blood anyways).
Worth noting is that Postmates doesn’t even require that you deliver by vehicle — a bike will do. Better yet, there are no startup fees or time commitments with Postmates and all you’ll have to do is pass a basic background check to get started. Once Postmates verifies your identity, they’ll send you a delivery bag and a prepaid card (in the mail) that you’ll use to purchase delivery items.
Use your credit card’s cash advance feature. Some credit cards will allow you to withdraw a certain amount of cash by using it at an ATM. This can help you come up with cash in a hurry. However, the interest rates on cash advances are usually much higher than the credit card’s usual interest rate, meaning that you will eventually have to pay more.
