I see no problem with reposting the item right away. However as Panache said it would be best if the description was perhapse made clearer, or more details were given. I've no idea what item you were refering to Squeaky. Does the price need to be adjusted also? If there was absolutely no response to your for sale post then perhapse it would be best to give the item a short reprieve from the want ads and post it again at a later date.
