fishy dark souls promotional items

[DESOUL]

I just bought a sif statue that was done by link dead studios from an ebayer. I was very happy even though i spent so much on it because (from my knowledge) its really rare (same as the looking glass knight statue). To my surprise (and lack of enough background checks), the same seller sold around 2 or 3 sif statues before, and so many more looking glass knights too.

The seller describes them as promotional items and he says ' You're unable to get one of these unless you have a business deal or contract with the studio!'

I really dont like that sentence. does that mean:
a) theyre not purely promotional items
b) the company itself is selling them unethically.

sadly i already spent so much on it and everything else clicked afterwards >_< wouldnt have bought it after all this 'self analyses' so its all my fault anyways, but still how does this guy keep having all those 'promotional' items?
