Legal Question in Business Law in California

Refunds are either (1) a term of the purchase agreement; or (2) a gratutitous customer service. If a refund policy is not part of the purchase agreement (e.g. it is posted on the wall or on a purchase order), then a store need not provide a refund for a product that is not defective.

In your case, there appears no agreement to accept returns and provide refunds. Accordingly, you do not have a "right" to a refund, and the store can refuse to provide a refund or put conditions on the refund, such as a restocking fee.

A few contracts require a "cooling off period" or a period during which the buyer has a right of rescission. These rights apply to specific types of transactions, and your question does not disclose enough information to determine whether the rescission right is applicable, in your case.

If your transaction is over a typical consumer good - e.g. clothing, food, office supplies - there is not a right of rescission or a right to return the product for a refund, except as noted above.
