Saw these in my local store today.
They are in a plain white box with black printed writing on so not easy to spot. They were on the same shelf as the other masterplug products like hdmi cables (£2.99), scart leads (39p) etc etc.
You get 4 sockets and 1 remote control.
I used the picture from Argos site but from memory they look identical. Home Bargains said the RRP was £29.99 i think.
Bargain if you need this sort of thing.
