"Excellent service!

Sporeshift have consistently got the best service of any online provider I have used. From the time of order to delivery the communication is great. I frequently wonder why other businesses can't to it the way they do. Excellence in action. And no, I am not their mother ... just a satisfied customer and mushroom lover. :)"
