This is a universal fact that what is seen is sold. Imagine this scenario: A buyer comes to your supermarket in search of toiletries. But what suddenly happens with him is that his eye catches the visually appealing bottle of shampoo placed on the supermarket shelves when he is running his eyes over shelves for his requirement. Stop again… Now what did he locate? Right beside it, he spots the highly sought-after hair serum you've been searching for! And place it in his Shopping Trolley.
