Guys, if y'all like the Lily's so much, buy the box of them from the Duty Free brochure. It's a heart shaped box with about 14 chocs in it, all flavoured like a favourite pudding (sticky toffee, lemon meringue, cheesecake etc.) and all for just seven quid.
I'm guilty of buying them and cracking them open in the middle of a boring IAH-LGW flight at two in the morning when there's nothing to do.
