While in a rush this morning, I did not stop and check my receipt at Tesco today. I usually do that after paying for my stuff at the counters. I came home and realise one of the promotional item I bought has not been discounted at all. So later in the day, while on my way back from town, I stopped by Tesco to clear things out. The service staff checked the item and it is selling at a discounted price indeed. But why didn’t the discount register at the barcode scannerwhen I checked out this morning. Anyways, I was compensated for the price confusion.
