Listen, as a former seller and now a buyer of Incotex on B&S, I have some insight. Where I live I can't get nice pants like these made. Yes, I can go bespoke, but who goes bespoke for cotton pants?
I bought 4 pairs from a seller here. With shipping (almost 50 bucks) and some discounts, it was more than worth it for me. Under $100 a pair. I'm grateful for the service people do here. Where else can you get Incotex for this price? Seriously, there's no place else except STP, but they don't have good stock always... and they're still more expensive than people are selling here. No measurements either.

Besides, even 2 years ago, Mabitex were going for pretty much the same price. I have proof from what I charged and sold.
