BOGO

Yesterday I was driving down the hill from Vestavia into Hoover and passed a business that had a BOGO sign out front. I am an engineer by training and trade so spelling and grammer are not my strong suits.  I pretty much don't worry  if something is ok or not but; BOGO kinda rubs me the wrong way. I know that it is shorthand for buy one get one free but it looks  to me like it is just saying buy one get one, In other words it is really describing  what all commerce is all about. You go in and buy one loaf of bread and you get that one loaf of bread, BOGO. Why isn't buy one get one free BOGOF?  Buy one get another for 1/2 price would be BOGAHP. Maybe the powers that be feel that the average person can't handle 5 or 6 letters. If that is the case then buy one get one free could be described as buy one get two, BOG2 or BOGT. I realize that this little peeve of mine is useless because BOGO is fairly ubiquitous but I am now at that age where my filters are not as strong as they once were and I pretty much say what I think.
