I was looking for one of these earlier and the cheapest I found was £28 on Amazon. Then popped into Costco for a cheap and tasty spud and found this.
Don't know if nationwide but awesome deal if I do say so myself.
This is the switch version, not motion sensor. If anyone wants to find them they are right in the TV section, by the SD Cards and USB Sticks.
(not sure if I've put this in the right category)
