as someone who used to sell fairly massive volumes, i think there's one primary answer, one that's already mentioned - the days of deep discounting NWT merchandise are over.
during the glory days of B&S the prices were truly ridiculous, and add to that the feeding frenzy PSA's when an e-tailer (or a B&M that took phone orders - these were the most hilarious) would try to clear shit out and get sledgehammered after someone posted a thread. people back then were very educated shoppers (still are) and they knew what a truly "oh shit" price was, and during the glory days, a great item was being offered at an "oh shit" price EVERY DAY. sometimes every hour on the weekends. the deals got so plentiful that i bet most of us who were around during those times increased their clothing budgets significantly (unreasonably?) because there were so many deals not to be passed up. i know i did - that's actually 100% of why i resold - to fund my own purchases. i never set anything aside, like Spoo did to get his Ferrari.
when i was selling, i knew that there was a price point at which i knew i could sell a NWT item pretty much immediately, as long as it was a desirable brand, color and size. John Lobb and EG at 5xx, RLPL suits at 5xx, Kiton/Charvet/Fray/Borrelli dress shirts in the very low 100's, and so on. i stayed away from Incotex because of fucking Daffy's and the expectations they created, though
the items being sold today are still great, but very seldom do i see the prices of yesterday. if someone were to sell something at those prices, i bet they will be snapped up just as fast.
