Ibotta is an app that pays you back for things you buy at the grocery store. The reason I'm listing it here is because when you cash out, the money goes instantly (or almost instantly) to Paypal. I've never had to wait longer than five minutes to get my money from Ibotta! You can also earn from referrals there, too. However, you must have at least $20 in your account to cash out. Still, cashing out every week isn't unrealistic with consistent use.
Some of the best things in life are free and market researchers love to hand out new products in exchange for consumer feedback. If you like to try new products and have the opportunity to try them out for free, do some research and find the market research companies that offer products you desire to try. You can join campaigns and they will send the products or coupons to you to test them and provide feedback. You will generally have to fill out surveys and provide written reports based on your opinions. You will get to keep the products and they will sometimes even send you a monetary gift as an offer of thanks for doing the work.
