What is everyone's experience with the home parties for selling gold? I have one booked at my house in two weeks

It was my intention to take at least a few pieces to a local jeweler and send same to USGB and then have the company coming to compare prices but it didn't happen...
I think I have quite a few coming and I get 10% of everything sold as well as $100 to pay for appetizers and drinks (as long as the party yields $1000 which it will because my gold alone was $1100 a few weeks ago). I also get $50 for anyone who books a party.
Has anyone compared home parties? From these threads, it seems that jewelers offer much less. The rep said that she has found that jewelers are much less and that her company prices were competitive to USGB, sometimes a little more sometimes a little less and this is coming from customers at her party that actually take the time to compare. I do of course realize that she is a salesperson
Thoughts?
