maybe you don't know anything about customer satisfaction, communication and public relations. If you are selling this kind of product over web, still postponing deliveries and hold thousands of $ almost year and somebody visits you, you must be able to answer any questions and make your best to satisfy the visitor. Especially, when you will know, that visitor will share the info with other hungry customers through forums, boards and other communication channels on web.
what you say maybe works within some local business but definitely not on web base selling with six months delay..
