Thought I would join the sweet and choc deals ;) This 600g Party Mix pack (35Bags) includes Mars, Milky Way, Twix, Maltesers, Milky Way Magic Stars, Skittles and M&Ms.
I know the Treat Size bags are £1.39 in Tesco atm. If you buy a few different bags and take the average price, I would even dare to say this deal here is a better price? You get a nice Mix, and its £0.50 for 100g.
They also got the Nestle Treatsize 35 packs, 545g for the same price.
