I've been to several Cost Plus World Market locations around the valley, and for the most part they are pretty similar.
Service is ok, the rewards are fun, but I wish it didn't take $200 to get World Explorer rewards. I imagine if you find a lot of furniture here, it's quick to get up there. I don't really have any furniture needs and find myself usually getting snacks and knickknacks - so $200 takes awhile.
On my last visit I picked up some delicious Korean BBQ sauce, chocolate and Clearly Canadian. I haven't had Clearly Canadian since I was a kid and while it brought back memories I certainly wouldn't buy this often because of the sugar. I wish they would come up with a stevia version or something so I didn't have so much guilt drinking it.
The Tcho chocolate by the way is out of this world and I'm hooked. The chocolate coins were just for fun for the holidays because they are so pretty.
I like to stop by Cost Plus World Market every once in awhile, because you never know what you will find there.
