This is a discussion on playstation now question within the General PS3 Discussion forum, part of the Everything PlayStation; i got an email on 3/27. but i didnt do it til the next day. and i still have yet ...
I also received an e-mail on 3/27 and I got the code on 4/3 so it was a week later for me personally. It's entirely possible that they may be adding more people in phases at a time but really I have no idea what they're doing in regards to this.
If it bothers you enough you could probably contact them but I would assume the people staffing the phones probably don't know anything either. I'm sure that as long as you got the e-mail and accepted the terms they'll get you in eventually.
