The regular webpage worked fine for me, no problems checking out either. Not sure why it isn't working for everyone, it was pretty smooth. Good luck guys!
I saw the sign up with the new prices a few days ago (wednesday, I think) at the FYE in the Mall of America while I was in Minnesota. I didn't think anything of it, I haven't been keeping up with the prices since I've had one for a while.
Forgot to post this, but there were literally at least 20 copies of RA3 Premier at the Best Buy in Signal Hill, CA yesterday. They were out of Crysis and Orange Box, and I got the last Crysis Warhead (which I totally didn't expect because it said that that store was out of stock online).
