Waitrose and Tesco had this deal as well (not sure if still on). Now Asda has it. Sweets like Maltesers, M&m's, etc. with sweet sundays are reduced to £1. So if my math is right, 4 packets of sweets and a cinema ticket will be only worth £4. Thats a bargain. Not sure if available online. Here's the T&C:
