We're planning to open the renovated section of our cafe on Easter. In connection with this event, we were planning to give something back to our valuable customers who've been with us throughout. The idea is to have a special offer in place for the first 50 customers. Our target audience is people living in an area of 2 km diameter around the cafe. The question is, do we print postcards or use flyers for promotion? We would have to place the order within the next couple of days and spoke with the folks from Troi mailing solutions: http://www.troimail.com/ regarding the same. Hence, postcards or flyers?
