A more thorough explanation:

SANS FRAIS

sans frais (sawnfray). [Law French] Without expense.

Sans frais is a legal term that means something is done without any cost or expense. This term is often used in legal documents or contracts to indicate that a particular service or action will not require any payment.

• "The company will provide shipping sans frais for orders over $50."
• "The lawyer agreed to represent the client sans frais because the case had a high chance of success."

In the first example, the company is offering free shipping for orders over a certain amount. This means that customers will not have to pay any extra fees for shipping.

In the second example, the lawyer is agreeing to represent the client without charging any fees. This is often done in cases where the lawyer believes they will win the case and receive a percentage of the settlement as payment.
