Edit: it looks like Sony has clarified that this deal is NOT available from the PSN store as linked below, but rather was referring to the same deal available from various online and physical outlets. Sorry about that everyone :( Highly misleading front page if you ask me. As of right now (11/29, 2.30pm central), the deal is still available on amazon. Haven't checked other places.
However it looks like the deal has not gone live yet; it says 11/29/13 only. I tried to get a subscription but the price was still $49.99. I do not know if they mean a specific time zone. Curiously enough it also says "while supplies last". Uh?
Anyway, looks like a great deal if/when it actually goes live.
