Was in Home Bargains earlier and they were selling boxes of 30 cans of Coca Cola for just £4.99. This works out at 16.6p per can, not bad considering they cost 55-80p in shops/vending machines locally.
The cans don't contain anything to say they are part of a multipack either, so they are probably the type that shops can sell individually. They are made in England and have no foreign text or anything on either. :)
