Has anybody had any luck using discount vouchers with a local business directory as a way of collecting email addresses? I'm starting a wedding suppliers directory in a country town (40k people). I'm thinking of creating a page of discount vouchers from different suppliers. To get the vouchers, visitors would need to join the monthly newsletter. I'm thinking of a single page with about 10 vouchers on it. It might include deals from florists, wedding venues, DJ's, marquee & chair hire companies etc.
Love to hear people's thoughts.
