It is a super hard sell with very pushy salespeople *before* you join. Once you've joined, everyone is super nice and helpful. We were about to embark on a $300,000 remodeling project (gutting the first floor, adding an entire second storey, major, major remodel). We DID join DB and overall it saved us around $50,000 on that project. We've kept up our membership because I anticipate doing another major remodel on another house in the future. But if I *just* had to furnish a few rooms, I wouldn't bother joining, the savings wouldn't be as great. The place we saved the most was on the stuff that actually went into the house - appliances, cabinets, flooring, tile, that kind of stuff. After our major remodel, we had one bathroom we hadn't touched during the remodel. About 3 years later, we decided to go ahead and remodel *it* too. My neighbor had just finished remodeling a similar bathroom using high-end finishes like we were planning. She told me she spent close to $30,000 on her bathroom. We spent $13,000. So, yeah, DB can certainly save $$, but not always and their hard sell can a total turn-off.
Added: It cost us $3000 to join, but that was many years ago. I've heard it's more expensive now...
