Sweden could be a very big market for you. A pack of cigarettes is about 2 BTC here, so a carton for 7 BTC is a great catch with free shipping. Customs could be a problem of course, receiving cigarettes by mail from other countries is not allowed. However, a single carton should be sufficiently small and light to not be inspected, especially if it's coming from another country in the European Union.

You should consider some advertising on Swedish websites.

Btw, your site says you ship to Germany but it's not possible to select it during checkout.
