I can't find these on line but there were loads of boxes full of these in the Rotherham branch of B&Q today.
It's a permanent price as the £1.00 price is actually printed on the card insert (That is inside the clear plastic packaging).
I can't find an image URL for the actual item. I do have a photo on my computer if someone would like to enlighten me on how to get it on here I would be greatful.
If I don't manage on a photo, these are individualy packaged with white card board inserts inside a clear plastic blister pack.
They are great for the Christmas decorations! Mini versions of the timer we've all seen before with the analogue dials to set off / on times.
30 minute interval settings and upto 24 off / on cycles per day (That'll keep the burlars guessing while you are out).
