What are you looking for? Auction Ohio has estate sales and such, and I've seen good used things there that are obviously barely used in nicer homes. But I haven't looked in a while, and some items were definitely niche tastes. Plus, it's hit or miss and you have to move it yourself or line something up.

I used Morris last year and have been satisfied, but it wasn't cheap. I kinda feel like ya get what you pay for with sitting furniture. The guarantee is what I really paid for there. I can return for 5 years with no questions asked.

Some of the resale shops around, not thrift stores, will and do get good things. Especially timeless accent pieces and/or dining area types of things. But, not necessarily inexpensive. I've seen some very cool , lightly used couches come thru that I woulda bought.

If you want inexpensive, Big Lots has things but I'd wonder about durability, for sitting furniture. Same with the Freight places.

Costco has select items. Idk the details on returning it, but they seem to take things back if they don't work out. I've tried some things out there before and woulda given it a whirl, but only b/c it's Costco.
