I have one too many a code. But mind you its only for the FIRST issue, there are 4 more released that have to be bought, in case someone wants to read the complete witcher comic.

I already own the collected edition, but I can recommend it as a good comic. Nothing mind-blowing, but a very good read, well illustrated too. In fact, it was a very positive surprise, since I was rather sceptical about a Witcher story written by a non-Polish author.
