i.e. / e.g. have you ever discovered that a vinyl you've had for a long while (bought from someplace else)- but not yet played- is faulty and so you order another but from amazon and then swap the two and claim a refund?

Amazon are very generous with refunds you see. Wondered if anyone else has actually done this, cos I'm thinking of doing it with a box set that I've finally got round to playing and discovered that alas 1/2 the discs have faults.
