Not sure how it is in Germany, but in The Netherlands these 'legal' substances are being sold online and delivered via regular mail. They are not illegal because the law doesn't forbid selling them, but they will eventually do that (Like NL is working on making 3MMC illegal). This is mostly a cat and mouse game with the law and drugs.
