DNS ... I'm not trying to debate the business practices of a dealer. My points surround individual to individual transactions.
While I did liken the cash price vs trade price to when buying a car, it has nothing to do with the business viability of a dealership or gun store, rather an individual engaging in SIMILAR activities ... what I consider shady practices ... in order to milk more $$ from a trade.
Individual to individual isn't necessarily about making money, rather than trading something I can live without in order to get my hands on something I would like to live with.
Simple ... FMV to FMV and cash can make up the difference. I don't see the point of artificially altering real world value.
If your standards are different then I can respect that just as I would hope you could respect mine.
