Winning people over

I've never bought anything from Argo Tea.  After two weeks of satisfying sidewalk samples all around the loop, today Argo invited people inside their store for free coffee.  I was able to see the store, get free coffee, and sample more amazing tea as I waited.  EVERY drink I've tasted there has been refreshingly satisfying.  They've earned a new customer. Marketing done well.  Valuable lessons on how to sell products/brands/ideas to people who would otherwise not care ...  now how do I properly apply this method to the things I want others to "sample"?
