Stereophile Scamming Subscribers?

I just got my renewal notice in the mail. I had previously subscribed for 3 years, and now it was expiring. I have been a subscriber for over 20 years. The notice stated I could renew for the low, low price of $33/year if I commit for 2 years. I figured I would go online and renew that way. I searched out Sterophile.com and lo and behold, a NEW subscription costs only $15/yr with a 2-year commitment.

What are they doing??
