Refunds are only available when it is unopened with factory seals intact.That’s true, but in the past a customer with a defective record was sometimes given a refund depending on the store’s policy. Defective product was returned to the distributor for credit.
Since the resurgence of vinyl, record labels will not take back an album for any reason. The burden is on the consumer and the individual vendor. Music Direct would not even exchange a defective Zeppelin LP for me, whereas Amazon has no problem doing so.
I agree that the cost is built into the price of each album. Have you noticed the price of new vinyl continues to rise?
