The Bellarom Rich Chocolate is the best milk one - there's one with whole hazelnuts too. The single-origin ones are excellent dark chocolate, but even the basic 39p bars are better than the abomination of Kraft Dairy Milk.

There is an Aldi in Tooting, but as it's opposite a Lidl (not one of my 3 local ones!) I use Lidl just because I've already read all the packaging and know which juice is real and not 'nectar' (ie 50% water plus sweeteners), etc.

Local Lidl is redeemed by having spaceships back in stock yesterday (and last 3 visits they've given me an extra Stikeez, too. So Quatlet will be well up there in playground bragging stakes today!)
