I don't really buy drugs or a lot on the darknet, but I thought I'd put a review here for www.freevirtualmailbox.com - very cool people that I've worked with a lot.
Do a lot of dropshipping with them as well. Had many items sent to them and forwarded internationally.
Anonymous domestic and international. They don't open any boxes.
I figured for you guys you could use as a middle man to avoid detection. Or something ;)
They accepted Bitcoin of course and Dogecoin too if you're a fellow Shibe.
+1 for me!
Also I just saw they have a copupon and you get $10 account credit. Not sure if it still works but try "Promo10"
And now every virtual mailbox are red flagged on international waters heh
