Just about every morning you'll find people at the Bay Area Rapid Train Station(called BART) giving out different freebies such as: new coffee drinks, candies, newspapers, gift cards etc. Why? The bay area is one of the hottest marketing test markets because of the diversity here in age, gender, race, nationality etc. To get a flavor for the different types of marketing groups, I often check out the Craigslist ETC. page which has a unique listing of marketing test study groups. You can often get a one time payment of 50.00 to 100.00 for participating in some type of quickie marketing survey and or study. Check it out for yourself here at Craigslist Etc. page.
