For non ultra luxury goods, this is true. But in the world of the $1M handbag you don't ever offer a discount, because if it's only $500k then obviously it's not as good, is it? Worse still, the customer who handed over full price last week is seriously pissed off because they no longer have a million dollar bag and do you think that they'll be back next year paying full ticket for the bigger, better, $2M version? Not a chance.
Naim do not make $1m handbags, nor even $1m hifi. They are not a vertically integrated operating model and they do not own their distributors or retail outlets (all of which is true for real luxury goods).
Despite their goods being sold by supposedly competing retailers, there are no retail discounts advertised anywhere.
Hence this increase in the "recommended" retail price will apply everywhere without exception.
