From the announcement:
December Sale. 20% off all orders of £40 or more, This sale runs until 31st December 2013.
Unfortunately the first week in January will see price rises applied to some of the items on the web site. I have not increased prices for nearly three years since taking over the business but rising cost have mean I finally have to apply increases. Hopefully the December Sale will let you get hold of some goodies before the increases kick in.
