3 packs of 30, once-a-day unbranded Cetirizine antihistamine tablets for just 1p. The reason for the price appears to be because they have a BBE date of July 2016 - but for people like me with chronic year-round dust allergies, or pet allergies or if you get hayfever early on (as we seem to have summer earlier each year) or even if you just don't care about BBE dates (as i don't!) it's perfect. Postage is £1.99, so the whole deal for 3 months comes to £2.00. Only one order per customer allowed though (1 order of the 3 box bundle) For comparison, they're usually £0.69 per box - still cheap but obviously not as cheap as 3 for 1p.
