Unfortunatly Plux-X reversal is no more, they were selling Tri-X reversal.

Whne the Plux-X WAS available, there was no problem for anyone to order it, as long as you ordered about 20 rolls at a time (400Ft each) The Tri-x has the same sort of Minimum. The reason being that they have to get the Regular 8 Dies out of storage and set up the machine - which no doubt will cause the wastage of a couple of thousand feet of film.
