Please be careful when ordering from relatively new sites. I ordered 250 dollars worth of MDMA from a vendor claiming to be Interways on the market Evolution. I FE'd because I've read reviews of him on other sites and I figured I should be good. I just checked today and his account was disabled so I guess I can assume I got scammed. Just be careful and check around and make sure the account is the real deal. Don't be a dumb ass like me. I had to rush to make this purchase due to personal reasons, but that's no excuse for being an idiot. Stay safe everyone.
Just compare PGP keys and write an encrypted messages and see if he answers(if he is able to answer, or rather, read the message, you're good to go).
