If you want to help shape products in their early stages, joining an online focus group or answering survey questions is a great way to make extra money online. They don’t pay as much as some of the other options we’ve highlighted, but you can join groups on sites like Survey Junkie, Swagbucks, and IPSOS that pay out through Amazon gift cards, check, or PayPal. You’ll be asked to provide a bit of information about your demographics (age, location, etc…), but after that you can get going making money through surveys.
Finding items at a garage sale that are worth significantly more than what you paid for it can be tricky, but can be done almost every weekend during warm months. You want to stick to items that make it worth your while to resell them. Taking the time to market a 50 cent figurine that sells for $5 is not worth it as opposed to a $50 cabinet worth $150. Just because there is large margin does not always mean it would be smart to resell it.
