Having been in retail floristry for 20 years, I am a believer in Yellow pages book adverts, some years ago I had a 1/2 page ad - yes it was expensive $12,000.00 - but it certainly gave me a high profile & alot of work both locally and for NZ & Worldwide. I was a very high sending member(top 20) of Interflora for a number of years. The yellow pages internet listing, I don't think is as good as the book but I think you have to be seen there. of course the best advertising is word of mouth and repeat business.
