I regularly shop (and even consign) thru Consignment stores, and some that were already mentioned, but some overlooked in Hendersonville are:
Kanuga Outlet, and The Furniture Barn, both close to downtown.
Not Consignment but might want to check out...Needful Things which is a large Antique Mall with antiques or previously owned items off Hwy 26 in Hendersonville.
Also, Frugal Decor and More off Sweeten Creek, is a good one too.They're a family owned company, and have a Sister store, Rudy's right beside them, that is mostly new decorator items.
My favorite is Select Furniture Consignment in Arden, right off Hwy 26 at the Airport Road Exit. Owner is a cool lady and very selective in what she sells, so always a great selection there. I go often as she moves items quickly thru her store. Some new, but mostly consignments.
By the way, a lot of these stores are closed on Monday.
Also, don't overlook "Craigslist" as I've purchased and sold items there as well...In Dallas, TX, Charlotte, NC and Asheville, NC...
Enjoy the hunt
