I have a favor to ask of members who sell items here. If you post an item with an email address and ask people to email you if they are interested in your item, ANSWER THE EMAIL. This applies whether you still have the item or not. It is common courtesy in my book.
Nothing is more frustrating than seeing comments appear on the thread after you know you have sent an email. Losing the chance to purchase the item is not the issue, it's the lack of a reply.
