Wholesale what?

Have you come across some insurance advisers at a mall? I often do. They usually blab about personal and life insurances that they are too insistent you could actually exchange face with them. It is always an annoying experience for me that is why I try my hardest to avoid them. Recently, my interest was caught by the catchy question on a pamphlet handed to me by an insurance agent and it reads: What is Wholesale Insurance? The brochure did not say much about the title so I just followed their invite to visit their website.
