I understand your logic and thanks for coming back to list the price range. Your sale thread was used for reference on a current WTB, but only good for showing the mirrors and not for price. What I do is go back to my first post and in bold I type
SOLD as the first word, then again right next to the price. I also post that they are sold as the the last post, and use bold again. I make it real obvious for all. I'm not one to tell others how to run their life, but this is what I do and you can take it or leave it. Works for me. I used to wipe the price out, too, till it was suggested by staff we leave it up for reference, and that makes sense to me. Have a good one
