english: In the real world, customers come from more than one direction, and businesses are free to compete with marketing strategies, by differentiating their product line, and with price cuts, but at the heart of their strategy, companies like to keep their competition as close as possible.
non_english: U stvarnom svetu, mušterije dolaze iz više od jednog pravca i firme su slobodne da se nadmeću sa marketinškim strategijama izdvajanjem svojih linija proizvoda, ili sniženjima, ali kao srž njihove strategije, kompanije vole da drže svoju konkurenciju što je bliže moguće.
