The site opened up at different times for the different time zones. The reason some of you couldn't get to it right off, is because your time zone wasn't open yet.
I was able to get in and according to them, I will also receive my coupon for free cheese in the mail. Kraft is a reputable company and I can't imagine them NOT honoring everyone. If they don't for some reason, I bet contacting them and complaining would result in them sending some pretty good coupons in the mail! LOL
PS. Hey! I just noticed that I am now a Junior Mommysavers Member! LOL
I can't believe I have made that many posts already in just one week! Haha!
