If you're a regular shopper at Marks and Spencer (M&S), then you'll probably have heard of the high street giant's current 12 Days of Sparks promotion, which is offering free goodies every day to people who have and use the Sparks app.
The promotion sees Sparks customers offered a new daily reward every day from December 1 until December 12, with prizes ranging from free festive treats such as light-up biscuit tins and the coveted gin snow globes, to vouchers for money off flowers and knitwear.
While the items on offer might sound amazing, not everyone is impressed by the things they've found behind each door of their virtual calendars, with some shoppers calling M&S a "disgrace" for handing out prizes that aren't "worth" the trip to their nearest shop to claim them.
