Lloyds Pharmacy are giving a 10% discount on their electrical goods.
For example the nasal allergy reliever (the up-the-nose-light-sabre thingy) is now £13.49. They also seem to be doing a buy two items for extra savings. So you could buy the above reliever and an ioniser for less than £20.
Didn't see when the closing date for the offer is, but hurry while shops last!
