Time to update your site with that information. It is not clear to me that if it was an ebay sale then it can't be used. Look at your wording for it. It even talks about an 'auction'. Leads me to think its for eBay. And besides, why not populate it so the variables can be used logicvally instead of trying to decipher what will work for this site verses that site verses that payment processor, etc. It is a straight forward price varible.
Too many things in ejunkie are like this and cause these questions to keep coming up. It would be simpler to straighten out the site and clear up that stuff instead of taking theses questions all day long.
Also, what about sale_price? it only shows the rounded dollar amount. Shouldn't it show 59.00 instead of just 59 as a general rule of formating.
