This is not an unusual practice in magazine subscriptions, and it also occurs with things like credit cards. A company will send out different offers ($X for Y years for a subscription, or $W annual fee with Z% interest rate for a credit card) -- with different values for W, X, Y, Z to different potential new or renewing customers. They are trying to figure out an offer that maximizes their revenue, even taking into account the few subscribers that will leave. Different demographic groups can even get different offers. Welcome to the statistics of marketing. If you are an outlier, your can passively quit (and thus contribute to their experiment), find a different channel to purchase, or call them up and negotiate.
