A Moscow-based bean roaster has set up an online marketplace accessible only with Tor, the software that allows anonymous browsing on sites that aren't otherwise accessible. Customers who want to make the most complicated coffee purchase of all time can download Tor, visit Chernyi's dot-onion site, and then use Bitcoin or Qiwi to purchase a bag of coffee. After scoring the sort-of black market beans, buyers will receive the coordinates of the shop's physical location, where all purchases can be collected.
This should be stickied in /r/DarknetMarketsNoobs . If you can successfully order coffee, then you are ready to order off the DNM's.
