A very "special" offer from Asda

I went to my local Asda a couple of Saturdays ago. They have some rather nice "Mangal" spice mixtures. There were 4 or 5 large red & yellow labels along the front of the shelf proclaiming "48p each, 3 for £2!" Eventually I found an assistant who looked like her IQ was into double digits. After a few minutes intense pondering, she agreed that it wasn't a great bargain, and removed all the labels. I went back a week later. Not only had 3 of the labels been replaced, but they were interspersed with a second offer - "48p each, 2 for £1!" I can't make up my mind whether I'd like to meet the person who put up those labels or not. I suppose it could be quite interesting in a scientific, natural-history kind of way. On the other hand, I find it hard to handle the knowledge that I share the planet with people like this. But what really bothers me is the thought that the manager who authorised those labels to be displayed probably earns twice as much as I do.
