Here’s an interesting idea. You all know about those universal keypads you can use for TV, VCR (if someone still use it), DVD, and other tech devices. You can order custom silicone keypads printed with your logo on it. Then, give away keypads as a gifts. You can give them to loyal customers, or organize some quiz on local radio, give a coupon for free keypad in newspapers, … There are so many ways but people who get your keypad will think about you anytime they get keypad in hand.
