A agree with some of the posters that the prices are generally a little high. However, I am also a recent grad who had just started working when I made my purchases so I'm not exactly a furniture expert.
While this is a consignment store a lot of the items are not exactly used. These items are from the World Market Center and they were display pieces. That is how I found my dining room table. The trick is to be willing to wait for items to go on sale. I found the table and then waited about 2 weeks, when I went back to check it was down a couple hundred dollars. Additionally, I sold my old table through the store (they get half and you get half) and put the money toward purchasing the table.
I also purchased a large bedroom dresser through the same store. That one was a truly used piece that someone was consigning. There is a system regarding price reductions and when you can ask to negotiate with the seller (the staff is really good at explaining it). I made an offer and it was accepted.
Overall it was a good experience and if you're willing to put the effort it you can get a good deal.
