Well also very often a retailer's return policy will be more generous than is required by law because their research shows them that it ultimately increases profit. In the US you can expect to be able to return opened and slightly used merchandise. It's easy to abuse, but it doesn't get abused nearly as often as one might think. It's frowned upon socially to buy something with the intent of likely returning it, except in some cases like online clothing stores where the nature of the product being purchased and the method of purchase necessitate returns (in this case it could be said that the returned product was defective for the purposes of the customer).
