It is like impossible to get. I tried it 7 times and every time it says duplicate product key. And I was refreshing nonstop until I saw a new code but I still failed.
Yup, you are probably right. I, for one, am locked out. I immediately was guessing 0-9 when I first saw the code drop and then it was not after I tried all the numbers that I noticed your tip. -_- I am such a dope.
Thanks for the code drop anyways.
Edit: All the codes have been taken by ninjas.
