I get sick of this happening, not just in Aldi, and bargains that don't show on the till receipt, I was in Morrisons the other week, there was a three for two offer on coffee - but when I got home I'd been charged £3.79 fior each jar. Go get your money back for the chocolate that never was - look at it this way, a bar of choc isn't going to break them, and so why woud you lie about something like that - it's not the money so much as the principle of the matter, being charged for something you didn't have.
