1 / 8A man in the UK recently experienced such a mix-up. This one case, though, had quite a happy ending.2 / 8Nick James, a 50-year-old man from Twickenham in the UK, had recently placed a click and collect order at Tesco, a global chain of supermarkets. 3 / 8In the order, James had selected Apples as part of the grocery. As James went to collect his order, he was surprised to find that it wasn't actually Apples that the supermarket placed in his order, it was an Apple iPhone SE.4 / 8At first, James was as surprised and confused as we are upon knowing of this. He double-checked his credit card bill for the amount deducted from it. 5 / 8Convinced that he had actually paid for Apples which he could eat, the presence of an iPhone SE instead seemed like a huge mix-up.6 / 8It was meant to appear so, but be assured that it was no mistake by which James got his iPhone SE. The brilliant ruse was, in fact, a marketing gimmick by Tesco wherein the supermarket chain is handing out such gifts to unsuspecting buyers. 7 / 8The exchange is being termed as Super Substitute and is leaving smiles on customers' faces since it has started.8 / 8Taking to Twitter, James thanked Tesco for the device. He wrote, 'A big thanks this week to @Tesco & @tescomobile. On Wednesday evening, we went to pick up our click and collect order and had a little surprise in there - an Apple iPhone SE. This is not the first such incident wherein Tesco has handed out goodies. Another user named Kirsty Marie recently shared her experience of shopping at a Tesco store. Much like James, Marie received a pair of Airpods in her order as a 'supersub' by Tesco.
