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.
Uno navega por el sitio, uno elige, paga con la moneda encriptada bitcoin, introduce una dirección, preferiblemente no la del domicilio, y espera a que su producto llegue por correo, lo que casi siempre sucede.
