Stop editing the contents of sales threads, post-sale? If you must put 'closed', just add it to the topic without removing the initial details. The forums are one of the best places to get an idea of sales value of items based on sales history. Do the community a service and please leave sales details intact post-sale. Thanks in advance.
I concur it's helpful to see what things are going for so we have a balanced value on goods for vendor
While I would like to see details, I think it is up to seller/poster on whether or not they want to disclose.
I will start doing that for you and everyone else when I sell rares and things. Would definitely be nice to have more reference looking back.
