I recently bought an area rug from Joss and Main, and I have to say I was quite disappointed with it. While the quality was awesome, the color was quite different from what they showed online. It is more of a mint green, but it looked more like a sage green on their website. I would be very wary of color variations if you decide to buy something from them. You can't return most of their stuff.
I have bought several pieces of furniture from Pottery Barn online, and it has been mostly positive experiences. The one time I bought a coffee table from them that turned out to be a much lighter brown than what was pictured in the catalog, they took it back and gave me a full refund, including the shipping.
You might want to check out the furniture at costco.com. If you have any problems with your purchases, they will refund your money, including shipping. I'm pretty sure you have to take it all back to the store yourself though. Good luck!
