I have just been informed that TOTS are ending there Halloween licence and ergo not selling the masks anymore !
Here is what the seller over at Movie Figures Ltd told me.
‘‘Until the shipment is actually on the sea the dates move around. It shouldn’t be much later than March as Trick or Treat Studios are discontinuing the Halloween licence at the end of this year so can’t produce any further stock after then.’’

Link to the listing if you want to make an order in the UK !
