wont the deals dry up??

[Vince Chaudhuri]

hey guys..
I am new to this so pardon my naivete. But why are people so open to giving out such information. In other businesses, bussiness methods are kept secret. If everyone knew how to find deals, wont they dry up?? Also, in business, its very valuable to be able to do things in a 'different way'. If we all use the same method of marketing, be it valpak, etc, how is that effective. Please eluminate.
