Statistically, more people still prefer printed material in their hands as far as advertising and promotions. A great way to reach a good audience would be with direct mailers.
Check out www.redtagprintsale.com and look into EDDM (direct Mailing). They offer competitive prices with exceptional quality work. Plus, they offer business cards, postcards, flyers, brochures and every other promotional print product out there on the market.
I wish you luck!
