Pukka?

Pukka tea bags? Two of the boxes below contain an extra 20%
more tea bags in exactly the same sized box, that's 4 more

24         :         20         :         24

But as you can see there is room for more more more.

Yogi Tea

Is the packet half full or half empty?  Check this out, 2 new packets of Yogi Tea, but the contents of both actually fit in one box.  No trickery involved.  But doesn't the printing inside the box look lovely, it makes me think the tea tastes better and justifies the ridiculously high price for 15 tea bags.
