I don't understand why we're having this discussion? The law has been there for a long time: you can't buy more than two packs of pain relief off the shelf at the same time (and that covers all pain relief, it doesn't matter what the name on the label is). It's to prevent abuse and if you do need more, you need to get a doctor to prescribe you. If you get people who have no idea what they're doing taking all the pills they can get their hands on thinking it'll make them feel better, you end up with all kinds of issues. If a customer doesn't understand that then that's their problem, but it's the same thing as Think 25. Sainsburys has a duty to uphold the law. If it doesn't, it'll lose a lot of money through fines and lost licenses.
