Choice is an essential instrument that either keeps one going on the right path or brings one to an unexpected end, which might turn out to b disastrous. 

In essence, whoever is buying a product will always try as much as they can to be careful so as not to buy a good product from the wrong firm. That's the more reason firms must be careful with their marketing strategy.  You can have a good product but not have a good marketing plan, if this happens, then the goal of production is defeated. Meanwhile we've seen companies that are not "up to standard" making good and rewarding sales just because of their wonderful marketing plan. When a product is continually and reasonably advertised, it has the tendency of endearing prospective buyers to itself. Such is the power of repetition-it creates impression.  A product that shows on TV on a daily basis has an advantage over the one that shows twice in a week. Buyers  are not acquainted with the potency, efficacy or durability of the product from watching ads, but there is this natural tendency of getting acquainted and being positively inclined to what you see and hear everyday. Repetition creates impression.
