Have you tried applying to Nielsen Home Consumer Panel? It’s a great way to earn prizes for the data you submit to them. Buy your groceries and scan them in when you get home, using the scanner they provide you with. Once you get the hang of it, it’s quick and easy. The longer you’re with them, the better your prizes will be!
If you’ve applied in the past, try again. They’re always adding new zip codes/areas where they’re accepting!
