It is really 25% off not 33%.

3 items at normal price X .25 = 75% of the normal price

No, it's 3 items at the full price. Total price 300% of the cost of
one. 4th one "free", freee for someone who bought 3.

So 4 for 300% of the cost of one. The average price for each one
300%/4 - 75%.


3 items at normal price X .333 = 99.9% of the normal price (call it 100%)

Therefore the first three are really at 33% off making the 4th one "free".
