We bought direct from NC in one of the "in stock" clearance centers when we lived in NC
Other places we've bought from:
Ashley (sleeper sofa)
Rooms to Go (sectional, coffee table)
Ikea (tables, chairs, bookcases)
Wayfair (headboard, desk, upholstered chair)
Target (barstools, side tables, storage)
Amazon (headboards, occasional tables)
We just ordered a leather set from Florida Leather Gallery after looking at 4 million pieces online and in person. Their prices were great, service was fantastic, and it's made to order. Will be here in 10 weeks.
We almost bought from Costco but after looking at the swatches, didn't love the leather color. They often have great sets in store but their online selection is great, too. FL Leather Gallery ended up being about the same price as Costco but I got to sit on it and look at all the leather samples in person.
We also looked at Article, Pottery Barn, West Elm, Joybird, Poly and Bark, and Burrow.
