You are not allowed to sell items (preorders) on eBay that cannot be delivered in 30 days.
http://pages.ebay.com/help/policies/pre-sale.htmlIf you want to sell presale items, be sure to meet all of the following criteria:
Guarantee that the item will be available for shipping within 30 days from the purchase date. Be sure to clearly state this information in your listing.
Clearly indicate in the listing that the item is a presale item.
The handling time specified in your listing should reflect the time from the end of the listing until the item is shipped to the buyernot the time the item is in your possession. Be sure to specify the correct handling time in your listing.
In the listing form, you need to use the default font size of 3 so people can easily see these sale terms.
Make sure your listing follows these guidelines. If it doesn't, it may be removed, and you may be subject to a range of other actions, including limits of your buying and selling privileges and suspension of your account.
This is from preorder sellers often stringing buyers along trying to get them to wait past the time that eBay disputes can be opened, and selling items that they don't have and might not get.
