Ok you won't see the "special gift cards" until you do the activities that are on Santa's Wishlist. and you have to have a linked Twitter account.
Here is what I did. Set up a twitter account and unclicked following everyone but you have to keep it public. You can set one up with any email though doesn't have to be the one you use for mycokerewards.
Then when you log into beta go through mcr and link onto your twitter. It asks you do do that right away.
Then go to Santa's Wishlist. There are three things this week - one is just a tweet and it will reward you with the option to get a 10.00 Nike and the other two require a picture and a tweet. I used pictures off of Google images.
Once you do those then you go back into your accound and click on Profile and then on the left there is a place that says Rewards. When you click on that it will show the special rewards assuming the two are still available (AMC,
Best Buy) this week. You can then redeem there. You will not see them anywhere else.
Also it makes no difference in the promotion if you are bronze silver or gold. I am bronze and got both Best Buy and AMC - I didn't want the Nike.
It took me about three days to figure this out and I do not like it and am not happy but I got the rewards for myself and then my husband and daughter also.
