I know one of the most important trick of marketing in a supermarket. This will probably change your thinking. I look forward to explain you with a story. I hope you read it till the end.
We begin.
Suppose, you are a buyer and you went to buy some stuff in the supermarket.
Let us consider, what do you want to buy?
All body stuff like soap, facewash, facecream, oil, powder and all such.
Suppose you always land in the supermarket to buy all body stuff because you know you get it cheap and even varieties. Is this clear?
And You don't want to buy some other stuff from supermarket(you may buy but suppose you are going for first time) Your primary point is only to buy the body stuff.
Now, you are a human being. And all humans need milk for there daily purpose. Do you agree? So the supermarket comes to know that you are not buying milk from the respective store, but as it is a daily need you must be buying from other places. This is checked at the bill counter. Whenever products are scanned, a computer programming detects what daily needs you are buying and what you are not.
So what computer does is give you 10% off coupons for milk for next 3 visits. What this does is change your thinking. You start thinking that as you got a coupon for next three visits you can save some bucks and therefore you buy milk from the supermarket. Am I right? This is tendency of every human. And as you start purchasing milk from there it becomes your habit. They change your habit to buy milk from them from the next time. And after it becomes your habit the milk coupons are no more offered but you starting buying from them that ends with there profit. And whenever you next time visit store without a coupon you still end with litres of milk in your bag because it has become your habit now.
This trick is used between all the daily need or monthly need products. They influence you to buy from them.
This is why you never get a coupon of the same thing that you purchased from the store. Consider this relevant to any of the stores, clothing store or any.
I hope this is clear.

Thanks for reading!:-)
And yes, always remember never look at the most lower rack in the supermarket. This is because, as a trick all good products are placed on the eye level to comfort the customer. And so cheap products at the below or to the top.
