I've read a lot of people here and on things like /r/drugs when DNMs are mentioned to only order domestic and never international. Is there a reason for this besides the added risk of customs? They give the impression that you'll be completely/extra fucked if they open the package. I figured realistically that if that occurs (your vendor's stealth is probably rather questionable if their packages are getting regularly seized anyway) you would just not get it, that's it. Unless of course it's large quantity, in which case you're fucked whether it's domestic or international and it's opened. It just seems the instruction to never order international is a bit overboard and unfounded in its claims as to why it shouldn't be done...but perhaps I'm misinformed.
I've not had a single hitch with my 15 or so international orders thus far over the past 3 months. Of course that doesn't mean it can't happen, but you can't just say I'm lucky, I guarantee there are veterans with far better success rates than me that would put the notion that you shouldn't order international to shame, especially those ordering massive MDMA weight regularly from the German vendors
I'm going to answer the question by only reading the post title.
