I think its important that you respresent your company and products as much as possible!
If you sell jewelry or clothing...make sure you wear them out in public so that when others make comments you can say "I sell this would you like to see a catalog or know more?"
If you sell cosmetics, again, make sure you wear them!
I think its also important to give gifts that represent your company too! Last year I gave a Tupperware Cake-Taker as a Bridal Shower gift to my friend. Before I left the Bridal Shower, I had 4 orders from Bridal Shower guests!
