Cash price
This originates from the days of the gold standard when "cash money" meant gold or silver, which holds intrinsic value as opposed to paper currency. By today's standards however It does not necessarily mean payment must be made in tangible form. Generally the term refers to the price paid up front for goods or services without any delays or caveats. A cash price is often less than the vendor's initial asking price in order to facilitate a quick sale.
"It is in really good condition. I'm only selling as I need some money right now".
"OK so what's your cash price?"
