I'm planning on using a price schedule based on lot size on doorknob hangers this spring. I was thinking of putting a low price (Starting at $20!) on the front to grab attention but only offering that price for a really small lawn. The area I would be targeting wouldn't have any lots this size, and the prices for the lots in these neighborhoods would be the prices I want. For instance 0-8K lots would be $20 8-13K lots would be $28 13-18K lots would be $34, call for pricing above 18K. Then only place them on lots over 8k. What do you think? Good marketing? Ethical?
