Mystery shopping can earn you $ if you sign up with the right websites or apps. I currently use a few of them to earn cash by doing quick mystery shops and other things. Mobee is one of them AND they are offering a sign up bonus.
Get a free $3 bonus from Mobee. Download the Mobee App and enter referral code XV6V when signing up. After you complete your first shop a 300 point bonus will be added to your account.
300 points is equivalent to $3. You can redeem your points for $5 gift cards for 500 points. You can get gift cards for sites like eBay, Staples, Starbucks and more.
Mystery shops range from 150-700+ points depending on the store and what you have to do. You can easily earn a few gift cards!
