Got it originally with the code.
So I wasn't aware it's a freebie now from C-Store.
Always only showed up as purchased.
Yeah I think this was likely done becuase they didn't use different codes to get it and as a result it spread through out the internet and thus there would have been no point to charging for it.
Despite the error with the single code going out (it was supposed to be different codes in every box, the printer screwed up, so they had to honor it), their contract still prohibited them from making it "free to everyone" until a few months ago. They would delete forum posts about the code, too.
Now that the contract is up, they put it in the c-store as a free item. As you said, no point in charging for it since so many people got it free anyway.
