Consumers have come to expect stores or catalog companies to offer a refund, credit or exchange when they return items. Sellers are not required by law to accept returned items unless they are defective. However, California law requires that retailers who have a policy of not providing a cash refund, credit or exchange when an item is returned with proof of purchase within 7 days of purchase must inform consumers about their refund policies by conspicuously placing a written notice about their policies, in language that consumers can understand, so that it can be easily seen and read. Some companies may limit exchanges or returns for credit or refunds on all, or some products. Some may not allow exchanges or returns for credit or refunds at all. But whatever the limitation, it must be conspicuously disclosed. Before making a purchase, carefully check the policy of the store.
