If you live (or have lived) in the following states, you are likely able to get $10 or $20 in as little as 20 seconds:
Arizona, California, the District of Columbia, Kansas, Massachusetts, Michigan, Missouri, Nebraska, Nevada, New Hampshire, Oregon, South Dakota, Tennessee, Vermont, West Virginia, Wisconsin
There’s a class action lawsuit that potentially gives residents from those states from 2003 until the present between $10 and $20. The residents have to have bought milk or other dairy products mentioned in the lawsuit. That’s a very low bar for most residents.
The website Bought Milk allows you make the claim in around 20 seconds. It is literally entering your first name, last name, email and clicking 3 check boxes.
I don’t want to take any more of your time, but if you think this is some kind of scam here’s more background from the Huffington Post.
