We just finished remodeling a kitchen. Had the good fortune of having already done a ton of comparison shopping before our contractor told us about Directbuy. We went in with our comparisons, and on our cabinets ALONE (same brand, same everything) we saved about $8,000. We estimate that on this project, we have saved about $13,000.
My wife read some reviews where people were complaining about the process for getting an appointment. I guess because we were referred to DB, that was less of an issue. Either way, their customer service staff is excellent. Absolutely recommend.
