    Supernaturally fast delivery

    The spirulina is exactly the same as other stuff I've bought, so quality checks out. It's relatively affordable and as the title suggests, the delivery time was insane. I ordered on Friday night, and it was delivered to my doorstep Monday morning in Rural Victoria.
