Maybe it is rare but sometime you can find a ’bogo’ sign in a certain store or promotion. It means ’buy one get one free’. Somehow it is becoming more common and some other area of business like insurance also have a bogo program. Sometime when buying a car the insurance can be included but there is another option to buy insurance separately.
There is a bogo program for cheap auto insurance and it makes it even cheaper. It is called multi car discount program.
