I'm a "written word" guy. I spend so much of my time either in noisy environments, situations with a high likelihood of interruption, or places with spotty reception that I really don't think of voice as a reliable means of communication. I can glance at a text or an email, then take a few minutes to formulate a reply, and I don't need to worry about much else. My success with phone calls is much lower.
That said, I'd be highly suspect of anyone who just says "Call me about your item". I'd think they're farming for phone numbers.
I might feel differently if it were something like "I'd really like to talk to you about the Dracula game that you have listed on Craigslist. I have some questions, could you please call me at..."
