1) Is the bonus content still available?
Supposedly through the 7th, no guarantees.
2) I have a registered account from a free weekend a few months ago. Someone posted earlier in this thread that they had an account and did not receive the bonus content when they registered their key. Anyone know what the deal is with this?
That was me who reported not seeing it and I don't know what the deal is. Maybe you had to buy time for December to get the offer and the free month with a purchase qualifies you. I'm not willing to pop $14.99 and find out.
To be honest, I don't think Amazon can sell a good AAA game with $60 retail price for $10 for a long time, so this is perfectly understandable
I'd point out that I bought it for something like $8 from GamersGate back over Thanksgiving but that's probably not the best data point
