+In some English accents, when you say "two for" quickly, it sounds like "two fer".

 So the phrase "two-fer" often implies a two-for-one offer.
 
-Imagine a bakery that has a holiday offer where you can buy two cookies for the
-price of one ("two-fer one!").
-You take the offer and (very generously) decide to give the extra cookie to
-someone else in the queue.
