I have just started selling cheap domain names not the cheapest in the world but I offer a fully serviced solution including hosting registration and webdesign with the customer support to back it up. (isnt everybody)

But any tips on marketing my site to sell them online or ideas about the pros and cons of this let me know.

James

Keep your domain price as low as possible and focus on hosting and design services. Low domain price can help you get more customers.
