Took me a while to pick it out of the image!

Here’s the deets in case it helps anyone else:

• 4 cans normally £4.35
• 3 cans yellow-stickered to £4.59

FWIW, way back when, I spotted a similar thing in my local Sainsbury’s. A pack of 4 apples cost more than buying four loose apples. I tweeted about it jokingly on a Friday, and to their credit they replied, and when I went in on Monday, the price had been adjusted.
