Another new thread :P
Some items in the game are rarely used despite being quite nice -- especially food, a lot of good food choices are overlooked because everyone just know Sole Sushi, Meat Mithakabob or Tanvanzian Tacos etc.
So if you try to get someone to buy a fancy product you wish to make :P It will need some advertising, and tell your customers why they should buy that fancy thing for :P
