一間公司可以點樣改變國家既文化?

問題應該是一間公司可以點樣改變客戶消費模式?
If the company charge the cheaper price for bulk order, the customer may buy more than they need?
For example, the single coke cola is $6.00 each.
If you buy two coke cola at the same time, you only need to pay $10.00. They people may buy one more, because the 2nd one is only $4.00.
The different pricing strategic will change the customer spending habits.
