I was at Kragen Auto Parts the other day and bought a casette adapter for my car. I realized it was defective 30 minutes later and went to go get a refund. When I got there the employee told me they have a no-return policy. I started to get frustrted because isn't it illegal not to refund the purchace of a defective product? On top of that isn't it mandatory to make your customer aware of the no-return policy before their purchase is complete? What can I do to get my money back?
