I have taken the matter in hand and have called the head office, and have been told;
"This range has been discontinued, and once supplies run out there will be no more"
So basically go and fill your boots and but up all you can.
P.S Boots in Bristol still have the old style Drynites (Booooooooo)
P.P.S Anyone know of any stores in the South West with the new style of Drynites?
