That 6/30/09 deadline may have been directed at me in particular. I had entered a lot of points around Christmas, and then they started piling up waiting for entry. Right after I entered the batch at Christmastime, I received a few emails from them saying that "all codes entered on (date) would be worth double points." At which time I had nothing to enter since I had already put them all in. Grrr. Which is why I was stockpiling for the first half of this year, waiting for another offer.
I received about six emails from mycokerewards, saying that I had to sign in before June 30th or the points already on my account would expire. Maybe it was because I hadn't used the account in so long? I entered everything and redeemed all but one point last week because of that email. (Before 6/30/2009)
As for the new site, I've seen some changes, but it looks pretty much the same to me as it did last year.
My most recent emails from mycokerewards still say the new site is "coming in July."
Perhaps rflorek, you're on a beta testing version? (Lucky!)
ETA: Just signed onto
www.mycokerewards.com and yes, it does look different today than it did last week.
