I have long discussed Customer Acquisition Cost (CAC). I realized that it could be fun to share my marketing basics, learnings, and experiences from my work as a sales & marketing director in the printing industry, as a self-employed individual, and from my international role as marketing manager for Roland. You disagree with my perspective, but if you don't, it would be great to discuss it further. Please share your views - my intention, as always, is not to be right, but to support the growth of our industry.
