Can you gat to Peckham, Zoe? Persepolis sells them for £1.79. I just called them and they're in stock. They're open till 9.00pm. Might be too late for tonight. Train from London Bridge or Waterloo East to Peckham Rye?
instead of traversing London on a Saturday and spending £ 6.60 for the pleasure plus prob 2hrs of your time navigating rich lefty protestors, you're better off buying a bag of almonds, sugar, cinnamon and making it yourself, not too hard if you're inclined
