Are you automatically due a $51 payout from Amazon’s massive Prime settlement? Or do you need to file a claim?

A Seattle judge on Thursday approved a record-breaking $2.5 billion payout by Amazon to settle a lawsuit claiming that the world’s biggest online retailer tricked U.S. customers into signing up for its Prime memberships and then made it difficult for them to cancel.

As part of that, millions of Amazon Prime customers are eligible for payouts

For instance, those who used Prime’s free shipping option three or less times in a year will get first dibs on the money.

The Federal Trade Commission estimates that 35 million U.S. customers are entitled to a slice of the settlement. That number is just a fraction of the 197 million estimated Prime members in the U.S, as of earlier this year.

The Prime membership program has become wildly popular over the years because it comes with multiple benefits, including free same-day, one-day or two-day s
