for free

At no cost

For free means without cost or payment, synonymous with free but more emphatic or casual: They're giving away samples for free, I got these concert tickets for free.

Some consider the phrase redundant since free alone conveys the meaning, but for free is standard in informal speech and adds conversational rhythm.
