I've checked estatesales.net, most of their stuff is too big for my room or not the right style (I have a small house with mostly "espresso" color furniture), plus since I live in a large metro area, there are already lots of savvy buyers I have to compete with.
I've tried overstock about 8 years ago, end up returning because their furniture came with cracks. Yes the shipping back to them is free but what a trouble hauling a dining table with chairs to "ship" back.
I highly doubt antique would work with my wife's preference of style and ergonomics concern, but I do take a look at craigslist just in case.
