I recently read about some of the fast moving consumer goods products and the companies that produce them. Actually, I just saw a list and wasn't sure exactly what an fmcg product was at the time. But anyway, you probably won't be surprised to learn that sodas, especially colas are some of the fastest moving consumer goods.
I guess that explains why there are so many soda displays in convenience stores and in supper markets. Most items are stocked in one area, but sodas are displayed all over the stores. Beer is also one of the more popular of the fast moving consumer goods.
