The smartshop prices dont work. Told by instore staff that a refund will be added to the app but that never happened on any of the four occasions I was forced to pay full price for most of my items reduced on my smartshop app. Its a scam to get you to purchase these items. They know you are not going to put everything back if a few things dont work. Well jokes on you Sainsburys because thats exactly what i did my 5th attempt. You are better off with Tesco clubcard prices, at least the price stated is the price you pay! im still waiting for my refunds but I wont hold my breath.
