This used to to be the trick to use with the 10 CDs for a penny offers to get out of buying the remaining required full price CDs. After you got the promo-priced CDs, you could send in a change of address form with an address where shipping costs made it unprofitable for them to send the remaining purchases. They'd send a letter back where they regretfully informed you that you membership was being canceled because they didn't support your new address. All you had to do was figure out some address in rural Africa or Asia. Everyone in my freshman dorm used that trick to fill out their music collections.
