Fantast Medway was a British SF mail-order bookselling business run by Ken Slater along with Tony Thorne. It grew out of his earlier Operation Fantast.
It was named "Fantast (Medway)" in spite of not being near the Medway (a river
in Kent) because Thorne had already had a shop in the Medway area, and they needed to distinguish the business from an existing "Fantast".
