All the things mentioned are to attract 'customers' to Winning Colours - WNBD success is dependent on customers discovering and using Winning Colours - and sharing/recommending to others in some shape way or form (be it going to neighbor house, buying bottle for friend, posting something on facebook or twitter - if they do that sort of thing, being picked up on a google or other search engine inquiry to a stain, mess, or problem (that WC can solve)...
This ultimately drives the larger chains to take you and your product seriously; this allows you to get your product in the face of a much larger amount of 'potential' customers (because of their traffic flow compared to independents, etc.).
I pick up brochures from time to time because they are free and could be informative.
