You guys with your non-eBay ad-ridden links. All you need to do is use this URL:
https://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemVersion&item=item_id
E.g. if the URL is www.ebay.com/itm/Pokemon-TCG-E3-Convention-Promo-SEALED-Pack-Kirby-Manhole-Pichu-Hoppip-JP-Back/292907204367, changing the url to cgi.ebay.com/ws/eBayISAPI.dll?ViewItemVersion&item=292907204367 will show you the actual sold for price.
