I used to take part in focus groups all the time whilst at university (I was your typical broke student!), and let me tell you, it is some of the easiest money I have ever made.
Focus groups are run by companies who want to gain insight into their products, services or marketing activities. When participating in a focus group, a company will ask your opinion on a range of things, and in return pay they you for your time – it’s that easy!
