These surge protectors are an essential item for your PC and electrical equipment. This one at PCWorld is currently on buy-one-get-one-free, meaning you get 2 of them for £14.99. This is the collect at store price, or if you prefer to get it delivered, then add on £3.99. I find their collect-at-store service very handy, I use it a lot myself, plus it saves you the 4 quid delivery.
