Search/Description Line/Additional Description Line

Actually you may as well let it run...ebay has already charged you. By 'second line' I think you mean the subtitle? You've already been charged for that, and in all honesty I always thought it a waste of money. There is plenty of room in the TITLE for a description of your item, it doesn't even have to sound like a sentence...use keywords only. Never use words like 'LOOK' or even worse 'HARD TO FIND'. Takes up too much valuable space.

Since I can't see the auction you're talking about, this is your call...if you think it would sell better with a complete rewrite, then go for it. If I knew for a fact I would attract alot more bidders with a better title, I would do it, but that's just me.

I think you can change your BIN (not positive on that one) but as before, you've already been charged a listing fee based on the price you have now. And I would never chage anything in an auction if I had even one watcher, that would be a real turnoff (unless it was for the better )

Good luck, whatever you do

I just found a page here
http://pages.ebay.com/help/sell/questions/revise-item.html#stores_fixed
what you can and cannot revise...it doesn't look like you can do anything with the BIN price you have (I just skimmed it tho).
Some good info on this page.
