If you believe in the law, don't buy smuggled goods. If you believe that anything is okay as long as it benefits you (possibly mitigated by how much it affects others) then buy smuggled goods.
illegal =! immoral
Law is made by people, it may by right or wrong. Law is just a set of codified norms based on numerous factors, some of which may be outdated or passed with wrong/malicious intent.
I would not buy stolen goods, under no condition. That would be immoral. But contraband? Come on, only policemen or custom officers, and other such perverts, consider it a crime.
