First of all, I must say that I have bad news. The other day, I was trying to unlock free items for my new penguin. But old codes gave me this error;

So, then I've tried codes which has been released recently. And they worked. But yesterday I tried those codes again, this time I get that error from all of it. So, we can say that Club Penguin removed all the unlock item codes.

If you want to have some coins, you can use coins codes. So this means, from now on you can only use unlock item codes for just money. This is bad for non-members, because they won't be able to buy lots of new items anymore, they will only use limited items. I think what Club Penguin's trying to do is making more money.
We know they have financial problems, so they are trying everything to solve this problem. Also I agree with them.
What do you think about this topic, penguins?
