Update : Have been doing a bit more research, Curry's put a security seal on all their boxes in store, whether on the shelf or in their store stock room, so this wouldn't work with them.

I'll update this with more information as I get it.

Those seals can be removed quite easily with a hair dryer, swap or remove the item and put it back on. The problem is that they will then sell the item on to an unsuspecting member of the public which is a bad move imo.
