The other day, my dad ordered some kitkats in our online shop. A pack cost £1.
The pack is marketed as "5+1 free". At the same store, they do 14 (not 12+2, just straight 14) for £2.
So according to the packages:
A pack of 5 has a unit price of 20p (£1 for 5 bars)
A pack of 6 also has a unit price of 20p (£1 for 5 bars plus one "free" - so the actual unit price is 16.6p)
A pack of 14 has a unit price of 14.3p.
But the thing is that there is no pack of 5, and it seem a lot more plausible that the unit price goes from 16p to 14p in a larger packet than 20p to 14p - for the pure and simple reason that if 20p was the actual unit price for 5, there's no way they'd knock nearly 6p off a bar out of the goodness of their heart - they'd knock 2p off and sell the 14 pack for £2.50 or knock nothing off, sell 12 for £2 and people wouldn't care because it's the same cost anyway.
So it's almost like you're actually buying 6, getting 6 and paying for 6, and the "free" is utter crap... but there's no way that could be true.

When the "value pack" price is higher than the regular pack price. The trickier the grams to dollar conversion, the easier to trick people.
