Topic: Invention Info Please

Any inventors out there that have advice for me. 

Is a patent pertinent?

Any advice is appreciated.

No inventors out there?

Well, has anyone presented an invention to QVC?  I ask because I received back confirmation of my appointment to show one of my inventions and would really like to know any tidbits that would make my showing more successful.  Maybe an insight into how the QVC folks work.
