If you bought milk in one of 16 states at any time in the past 13 years, you might be eligible for some cash.

It’s part of a settlement of a class-action lawsuit alleging some dairy co-ops conspired to reduce the size of their herds to raise the price of milk.

The lawsuit includes Tennessee, Michigan, West Virginia, Washington DC and about a dozen other states.

The payout is unclear. A $52 million pool will be divided among lawyers and every consumer who signs up. A website for filing claims says individuals could receive $45 to $70, but it also gives an example of a fixed $30 payment.

“Depends on how many people apply,” UW-Madison agricultural economist Robert Cropp, an expert witness in the case, said. “But I don’t think we’re looking at very many bucks.”

The deadline to sign up for a share of the payout is Jan. 31 at www.boughtmilk.com. At this time it appears so many people are heading to the website, that it has crashed.

You’ll be asked to provide your name and email address and confirm which of four statements apply to you.
