@johnjohnston thanks for this. You did send me down a rabbit hole. Best bit- – an upmarket ready meal range was £7.50 ten years ago, and is still £7.50 today.
– a high-end stores ‘Dine In For Two For £10’ has been £10 for as long as I can remember.
– my local supermarket had 400+ items in their value range, it’s now 91 (and counting down)
