Usually there are things missing from my order but occasionally there are items that I didn't order and I haven't been charged for.
Tonight it was a huuuuge tub of Lurpak spreadable, Finest beef and shiraz ravioli and a tub of fresh arrabiata sauce (think this might have been someone's Friday night easy dinner ) and cheese slices (bleurrrgh).
Apart from the cheese slices I'm quite impressed. Phoned Tesco and as usual their instructions were just to keep the stuff and for once I don't mind.
