4. JJ Friends & Neighbors (Johnson & Johnson)
Johnson & Johnson, the company behind many of the brands you find in your household, runs the JJ Friends & Neighbors program, where you test products before they launch.
This could range from smelling fragrances, to trying out a new shampoo, and other self-care products.
You can participate in group discussions, surveys, forums and various panels. Anyone can join, and as far as pay-outs go, the most common seems to be a prepaid Visa Gift Card.
