Retail?

The retail listed should be when the seller purchased the item. Some sellers are very sensitive if you ask the date of manufacture of a component.

Another vote for current retail as that is what it cost to
buy a new one now. And at the bottom of the deal, people
very seldom pay the asking price. So what does original MSRP
matter, value is determined at the point of sale.As long as
they aren't providing an inflated false list price, in my
opinion no harm with current list. If you are looking for
Boraxo Model F250XE Amp, you know a little about it and
probably what it sold for. Now records are a different story.
The add should state a 4.99 album new at Woolworths is now
20.00 for NM.

Quite a divide. I notice this issue lately since the past 3-4 years have seen a significant increases in MSRP - there is something about profiting in that windfall that rubs me the wrong way, I guess there is no definitive right or wrong on the issue, that is simply my personal take on it. I don't have an issue with a collectible like a Mac or Marantz rising in price, like a 67 Corvette, I have more of an issue with something like Manley gear that increased 50% in one year. But yes, you are free to buy or not buy, I get that.

Price for the item when new. Cannot list the current new price as often times the unit has gone through changes along with the price increases.
Straight forward answer it seems to me.

It’s hard to keep perspective on “Retail” when the likes of Nordost holds a yard sale like they’re doing today.
