this guy does not look like a scam at all, and considering buying from the site, although there is another site smokers-mall.com which has the same product for much cheaper.
You don't have to do all that Silk road and bitcoin bullshit.
And to OP: Yes, cigz.eu is a scam website, if they don't outright rip you off, then they will sell you stolen cigarettes, good luck explaining that to customs if they happen to seize it...
There are plenty of other much more legit companies (and they accept credit cards) doing this.
