You browse through the site, you make your choice, you pay with the crypto-currency bitcoin, you enter an address --  preferably not your home address -- and you wait for your product to arrive in the post, which it nearly always does.
Pregledavate stranicu, odaberete proizvod, platite kriptovalutom bitcoinom, upišete adresu -- po mogućnosti ne svoju kućnu -- i čekate da vaš proizvod dođe poštom, a gotovo uvijek i dođe.
