I've had booths in Medical Conventions in the Philippines for four straight years. I've had all sorts of give-aways and all sorts of prizes and surprises.
One of the things I've learned is that BAGS create lines. Yup, bags with the logo makes our dearest doctors line up. They Love It! I don't exactly know why but it works.
This is something I realized after seeing the long lines with Cycles in POGS (Philippine Obstetrics and Gynecology Society Convention). Other booths were offering all sorts of giveaways but The Bag Works.
