Remember Premise sending a 8" block of a 2x4 that was stamped with " What do we have to hit you with to use this stuff" I'm in the process of doing the same thing with 5" 2x4's It's for " High Desert Pest & Weed Control" , my business. I'm starting with 2,000 to test the results . I think it's better than mass mailing to the same people over and over which is one of my methods . Any feed back ???
