BOGOF means "buy one, get one free," but there are many different terms that businesses use to describe this kind of deal. One synonym is "two for one," which is self-explanatory. Another term that's often used is "50% off," since you're essentially getting a 50% discount when you're purchasing two items for the price of one. Other phrases that you might see include "double the fun," "double the value," or "buy one, take one." Some companies may also play up the word "free" by using phrases like "freebie frenzy" or "zero dollars down." Whatever the terminology may be, the essence of the deal remains the same: customers get more for their money.
