Answer: to save money, etc.
Explanation: when people see that they are able to spend less on something they automatically consider buying that product instead. although, quality isn't usually considered when doing it. after we buy the item we get curious about how much money you saved, but are we really saving?
we'll end up spending it elsewhere on another "cheap" item that is priced to seem less than another product. that is why we buy cheap things. it's appealing to the mind to think you've found a solution to your spending situation
or, maybe that's all the person can afford
