The reasons why people buy the sign

I recently talked to many people interested in buying some sign, and I wondered why they want to buy it ( I know it's weird to say that...) But still, the reason is so different, even purchasing the same product. So after obtaining the customer's consent, I would share some of those. It means to me because the value behind the product is much more important than the products itself, which is also the primary root that I want to construct.
