     Here's How to Get Your 6 Movies for 1¢Each Just Write in the Numbers of the 6 movies you want for

1¢each, plus shipping. In exchange (交换), you agree to buy just six more movies in the next three years,

at our regular Club prices (which currently start as low as $19.95 plus shipping)-and you may cancel (取消)

membership at any time after doing so. What's more, you can get two more movies for the low price of $6.95

each and you will, after that, spend much less on the movies you want.

     Free Video Magazine sent every four weeks (up to 13 times a year), with our Director's Selection -plus

many lower-priced cassettes, down to $14.95. And you may receive Special Selection mailings up to four

times a year (a total of up to 17 buying opportunities per year).

     Buy Only What You Want! If you want the Director's Selection, do nothing - it will be sent automatically

(自动的). If you prefer some other selection, or none at all, just mail the answer card always provided by the

date specified. And you'll always have 14 days to decide.

     Instant Bonus Plan. As soon as you become a member, you'll immediately have the right to our

money-saving plan! It enables you to enjoy more great savings on the movies you want-right from the start of

your membership!

     10-Day Risk-Free Trial. If not satisfied, return everything within 10 days, and then you'll get your money

back and there will be no further obligation.
